In a Flood of Remembrance

Piano

Softly, in the dusk, a woman is singing to me;
Taking me back down the vista of years, till I see
A child sitting under the piano, in the boom of the tingling strings
And pressing the small, poised feet of a mother who smiles as she sings.

In spite of myself, the insidious mastery of song
Betrays me back, till the heart of me weeps to belong
to the old Sunday evenings at home, with the winter outside
And hymns in the cosy parlour, the tinkling piano our guide.

So now it is vain for the singer to burst into clamour
With the great black piano appassionato. The glamour
Of childish days is upon me, my manhood is cast
Down in the flood of remembrance, I weep like a child for the past.

D. H. Lawerence (1885-1930)

Dinner Conversation at Our House

Dinner conversation Sunday, November 22,2009 (since family members don't always appreciate being identified in my blog, I have eliminated names.):
Speaker 1: It's nice that taking care of this big house isn't as time consuming as we feared it might be.

Speaker 2: Well, time is ALWAYS being consumed. The question is what are we choosing to have it consumed by?

Speaker 3: Time isn't consumed. Time is passing.

Speaker 4: What happens to time after it passes?

This is the environment by which I am surrounded!
(And I think it's cool :-)

From Generation to Generation, We Will Remember

Lord, you have been our dwelling place throughout all generations.

I just got the news that my great uncle Paul passed away this week. Now Grandpa is the only one left of the 10 siblings. It's hard to believe that nearly that whole generation has passed.Here are my Van Dyken Great Grandparents on their 45th anniversary. As I look at their eyes in this picture it just does seem hard to believe that they and 9 of their 10 kids have passed on to glory (though nearly all made it into their 90's, and Great Grandpa made it to 100).Here are Great Grandma and Great Grandpa just starting out with the first 4 of their ten kids: Anne, Dinah, Bert and Sadie. My grandpa was the next baby to come along.Here is the whole family - not sure of the year - in the 1950's maybe? Time like an ever rolling stream bears all her sons away --
-- very true, very true.

Psalm 90


Lord, you have been our dwelling place
throughout all generations.


Before the mountains were born
or you brought forth the earth and the world,
from everlasting to everlasting you are God.

You turn men back to dust,
saying, "Return to dust, O sons of men."

For a thousand years in your sight
are like a day that has just gone by,
or like a watch in the night.

You sweep men away in the sleep of death;
they are like the new grass of the morning-

though in the morning it springs up new,
by evening it is dry and withered.

The length of our days is seventy years—
or eighty, if we have the strength;
yet their span is but trouble and sorrow,
for they quickly pass, and we fly away.

Teach us to number our days aright,
that we may gain a heart of wisdom.


Relent, O LORD! How long will it be?
Have compassion on your servants.

Satisfy us in the morning with your unfailing love,
that we may sing for joy and be glad all our days.

Make us glad for as many days as you have afflicted us,
for as many years as we have seen trouble.

May your deeds be shown to your servants,
your splendor to their children.

May the favor of the Lord our God rest upon us;
establish the work of our hands for us—
yes, establish the work of our hands.

Long Time Coming

This is a milestone in my life, so, though it may be gauche I am going to post notes from my chalkboard today.
Today, for the first time in the 26 years since I learned it I had opportunity to teach
The Fundamental Theorem of Calculus.
Here is the proof (literally and figuratively!):TWENTY-SIX years later, I have FINALLY taught this!!

I usually use the overhead projector, but this called for the boards - ALL of them!

Plunge Downward

Grow not too high, grow not too far from home,
Green tree, whose roots are in the granite's face!
Taller than silver spire or golden dome
A tree may grow above its earthy place,
And taller than a cloud, but not so tall
The root may not be mother to the stem,
Lifting rich plenty, though the rivers fall,
To the cold sunny leaves to nourish them.
Have done with blossoms for a time, be bare;
Split rock; plunge downward; take heroic soil, ---
Deeper than bones, no pasture for you there:
Deeper than water, deeper than gold and oil:
Earth's fiery core alone can feed the bough
That blooms between Orion and the Plough.
Edna St. Vincent Millay (1892-1950)

Fallen Giant

One of the giants of twentieth century mathematics fell last month at the age of 96. He was called "one of the last of the greatest who worked in nearly every field of mathematics." He was called by one student, "very unpredictable and very wise," and a colleague considered him the most interesting person he had ever known.

Gefland never finished high school and never attended college as an undergraduate student. He went to Moscow at age 16 or 17 and worked odd jobs but was always interested in mathematics, attended seminars, and at the age of 19 was admitted directly to graduate school of Moscow State University. He worked in extremely abstract areas of mathematics, which most people do not even know exist, but much of his work has profound application as well, and some medical imaging tests that most of us benefit from at some time in our lives (such as 3D images created by MRIs and CAT scans) are possible due to his work. It is said that he sought not just to teach the rules of math but also the beauty and exactness of his field (my kind of guy!). He also had a sense of humor and was quoted in a 2003 interview with the New York times as saying:
“Mathematics is a way of thinking in everyday life. It is important not to separate mathematics from life. You can explain fractions even to heavy drinkers. If you ask them, ‘Which is larger, 2/3 or 3/5?’ it is likely they will not know. But if you ask, ‘Which is better, two bottles of vodka for three people, or three bottles of vodka for five people?’ they will answer you immediately. They will say two for three, of course.”
His obituary (from which I took the information above) can be found at

A Chainless Soul

Riches I hold in light esteem
And Love I laugh to scorn
And lust of Fame was but a dream
That vanished with the morn–

And if I pray, the only prayer
That moves my lips for me
Is–"Leave the heart that now I bear
And give me liberty."

Yes, as my swift days near their goal
'Tis all that I implore
Through life and death, a chainless soul
With courage to endure!
Emily Bronte (1818-1848)

His Own Words

David just let me know that he posted his reflections about being 2-years post-stroke on his website. I had posted mine below. If you'd like to check his out, click on DAVID at right.

Early Thanksgiving

We are so thankful to be where we are today and not where we were 2 years ago today.

Two years ago today I was sitting in the intensive care unit at David's side - not entirely sure he would make it through the night - and if he did, not sure whether or not he would ever walk again. He has come so far in these two years - not yet as far as he would like, but so far from where he was. We are so thankful!

(Here is the post I wrote that day asking for prayer, and I want to say "thank you" again to those who did and have upheld us in prayer. We have seen those prayers answered!)

Game Theory and National Policy

A friend sent me this link, and I found it to be one of the clearest explanations of The Prisoner's Dilemma I'd ever heard. As the speaker relates this to foreign policy and explains what it has to say about how we should most wisely interact with other nations, it seemed to me to be a piece of crystal clear logic. Who says you don't use math in everyday life?! Click here to go to the video you see pictured below.

Fall Stuff

I have a great new job, and I also now have no life, but although my vision is filled with the following nearly 24/7, I want to get some pictures up of fall activities for family and friends far away (and nearby too). There is a lot going on, and for now I'll let my family take it in, and I'll try to catch up over Christmas vacation.I move from one table to the other - to the floor - back to a table - keeps me from cramping up over long periods of time.We have a new house:Someday I hope to read some books in the new house.The boys (including David) are enjoying the pool.The boys are also enjoying the new experience of having a 2-story house.We continue to cheer on the Enochs cross-country team, and especially Anthony (who in this picture is hidden behind the second person from the left).We've had some weird - and beautiful - weather.Caleb has found his true identity as "ketchup boy" (aka "Chip" in his youth group).We are so thrilled that Mike and Amy and Sierra and newly arrived Ava live so near us now - in a home we can see from our new home! Another reason I'm eager for break is to have some time with them!We took a quick trip to one of our favorites - Knight's ferry:Here are my special guys at Knight's Ferry. I need to get back to my "task" and not lay it aside, but I need to record that life is going on in my near vicinity anyway, and I'm eager to rejoin it soon!

As for Tasks

The Suicide

“Curse thee, Life, I will live with thee no more!
Thou hast mocked me, starved me, beat my body sore!
And all for a pledge that was not pledged by me,
I have kissed thy crust and eaten sparingly
That I might eat again, and met thy sneers
With deprecations, and thy blows with tears,—
Aye, from thy glutted lash, glad, crawled away,
As if spent passion were a holiday!
And now I go. Nor threat, nor easy vow
Of tardy kindness can avail thee now
With me, whence fear and faith alike are flown;
Lonely I came, and I depart alone,
And know not where nor unto whom I go;
But that thou canst not follow me I know.”

Thus I to Life, and ceased; but through my brain
My thought ran still, until I spake again:

“Ah, but I go not as I came,—no trace
Is mine to bear away of that old grace
I brought! I have been heated in thy fires,
Bent by thy hands, fashioned to thy desires,
Thy mark is on me! I am not the same
Nor ever more shall be, as when I came.
Ashes am I of all that once I seemed.
In me all’s sunk that leapt, and all that dreamed
Is wakeful for alarm,—oh, shame to thee,
For the ill change that thou hast wrought in me,
Who laugh no more nor lift my throat to sing!
Ah, Life, I would have been a pleasant thing
To have about the house when I was grown
If thou hadst left my little joys alone!
I asked of thee no favor save this one:
That thou wouldst leave me playing in the sun!
And this thou didst deny, calling my name
Insistently, until I rose and came.
I saw the sun no more.—It were not well
So long on these unpleasant thoughts to dwell,
Need I arise to-morrow and renew
Again my hated tasks, but I am through
With all things save my thoughts and this one night,
So that in truth I seem already quite
Free and remote from thee,—I feel no haste
And no reluctance to depart; I taste
Merely, with thoughtful mien, an unknown draught,
That in a little while I shall have quaffed.”

Thus I to Life, and ceased, and slightly smiled,
Looking at nothing; and my thin dreams filed
Before me one by one till once again
I set new words unto an old refrain:

“Treasures thou hast that never have been mine!
Warm lights in many a secret chamber shine
Of thy gaunt house, and gusts of song have blown
Like blossoms out to me that sat alone!
And I have waited well for thee to show
If any share were mine,—and now I go!
Nothing I leave, and if I naught attain
I shall but come into mine own again!”
Thus I to Life, and ceased, and spake no more,
But turning, straightway, sought a certain door
In the rear wall. Heavy it was, and low
And dark,—a way by which none e’er would go
That other exit had, and never knock
Was heard thereat,—bearing a curious lock
Some chance had shown me fashioned faultily,
Whereof Life held content the useless key,
And great coarse hinges, thick and rough with rust,
Whose sudden voice across a silence must,
I knew, be harsh and horrible to hear,—
A strange door, ugly like a dwarf.—So near
I came I felt upon my feet the chill
Of acid wind creeping across the sill.
So stood longtime, till over me at last
Came weariness, and all things other passed
To make it room; the still night drifted deep
Like snow about me, and I longed for sleep.

But, suddenly, marking the morning hour,
Bayed the deep-throated bell within the tower!
Startled, I raised my head,—and with a shout
Laid hold upon the latch,—and was without.

* * * * *

Ah, long-forgotten, well-remembered road,
Leading me back unto my old abode,
My father’s house! There in the night I came,
And found them feasting, and all things the same
As they had been before. A splendour hung
Upon the walls, and such sweet songs were sung
As, echoing out of very long ago,
Had called me from the house of Life, I know.
So fair their raiment shone I looked in shame
On the unlovely garb in which I came;
Then straightway at my hesitancy mocked:
“It is my father’s house!” I said and knocked;
And the door opened. To the shining crowd
Tattered and dark I entered, like a cloud,
Seeing no face but his; to him I crept,
And “Father!” I cried, and clasped his knees, and wept.
Ah, days of joy that followed! All alone
I wandered through the house. My own, my own,
My own to touch, my own to taste and smell,
All I had lacked so long and loved so well!
None shook me out of sleep, nor hushed my song,
Nor called me in from the sunlight all day long.

I know not when the wonder came to me
Of what my father’s business might be,
And whither fared and on what errands bent
The tall and gracious messengers he sent.
Yet one day with no song from dawn till night
Wondering, I sat, and watched them out of sight.
And the next day I called; and on the third
Asked them if I might go,—but no one heard.
Then, sick with longing, I arose at last
And went unto my father,—in that vast
Chamber wherein he for so many years
Has sat, surrounded by his charts and spheres.
“Father,” I said, “Father, I cannot play
The harp that thou didst give me, and all day
I sit in idleness, while to and fro
About me thy serene, grave servants go;
And I am weary of my lonely ease.
Better a perilous journey overseas
Away from thee, than this, the life I lead,
To sit all day in the sunshine like a weed
That grows to naught,—I love thee more than they
Who serve thee most; yet serve thee in no way.
Father, I beg of thee a little task
To dignify my days,—’tis all I ask
Forever, but forever, this denied,
I perish.”
“Child,” my father’s voice replied,
“All things thy fancy hath desired of me
Thou hast received. I have prepared for thee
Within my house a spacious chamber, where
Are delicate things to handle and to wear,
And all these things are thine. Dost thou love song?
My minstrels shall attend thee all day long.
Or sigh for flowers? My fairest gardens stand
Open as fields to thee on every hand.
And all thy days this word shall hold the same:
No pleasure shalt thou lack that thou shalt name.
But as for tasks—” he smiled, and shook his head;
“Thou hadst thy task, and laidst it by”, he said.

Happiness or a Ham Sandwich?


Which is better, eternal happiness or a ham sandwich?

It would appear that eternal happiness is better, but this is really not so!!

After all, nothing is better than eternal happiness, and a ham sandwich is certainly better than nothing. Therefore a ham sandwich is better than eternal happiness.

Need a Reason to Celebrate?

In case you are looking for an excuse to celebrate, don't forget that "Mole Day" is coming soon!

Here's what it's all about (according to Wikipedia): Mole Day is an unofficial holiday celebrated among chemists in North America on October 23, between 6:02 AM and 6:02 PM, making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from the Avogadro constant, which is approximately 6.02×10^23, defining the number of particles (atoms or molecules) in a mole, one of the seven base SI units.

May I suggest as a celebration idea some "pi ala mole?"

Splinter Swerve

The Brain, within its Groove
Runs evenly-and true-
But let a Splinter swerve-
'Twere easier for You-

To put a Current back-
When Floods have slit the Hills-
And scooped a Turnpike for Themselves-
And trodden out the Mills-
Emily Dickinson (1830-1886)

Worth Repeating Right Now

Sometimes, exhausted
with toil and endeavour,
I wish I could sleep
for ever and ever;
but then this reflection
my longing allays:
I shall be doing it
one of these days.

Packed - My Life and My House

A lot has happened since I last posted, which is why it's been a while since I last posted, which reminds me, I need to add something to (or about) the last post - just a cool little related item. Since I last wrote we have moved to a new house. I have posted pictures of lots of different houses. The one we moved into is the one posted here. Of course the furnishings you see belong to the former owners. Right now, imagine the same space but with lots of boxes! I have lots to post about the move and the house, but I need to wait until my head has a chance to stop spinning. I had not packed a single box as of Thursday - couldn't - could not do it given my work schedule. Thankfully we have the most awesome friends and family in the world and that some of them also happen to own pick-ups! I can't say enough thanks to friends and family who helped us. They worked tirelessly, packing my/our belongings, transporting them, unloading them, helping us to settle in and on and on. More on that in a future post. For now, since life seems so serious and busy, and even math, which I normally have so much fun with has become more work than fun at the moment, I want to post something math-related just for fun. See if you can figure out how it works (or not). Either way, have fun!

Artful Whimsy

My boys and I have always had a fondness for the art of Salvador Dali and Rene Magritte. Many years ago Jacob, our resident artist, made a number of drawings inspired by the work of these artists. One of them is included at the top of this post. Today he decided to update the process using his computer knowledge. Below is what he created this afternoon inspired by his work of years ago.You should be able to enlarge the images by clicking on them.

I Sing

We're doing our family devotions in a rather unique way, I think - using a book that contains the history of hymns, the scriptures that inspired them, and the stories of their authors. Tonight we focused on the hymn I Sing the Mighty Power of God. Now I can't stop singing it! It was inspired by Jeremiah 51:15:
He made the earth by his power; he founded the world by his wisdom and stretched out the heavens by his understanding.
I sing the mighty power of God,
that made the mountains rise,
That spread the flowing seas abroad,
and built the lofty skies.
I sing the wisdom that ordained
the sun to rule the day;
The moon shines full at his command,
and all the stars obey.

I sing the goodness of the Lord,
who filled the earth with food,
Who formed the creatures through the Word,
and then pronounced them good.
Lord, how Thy wonders are displayed,
where’er I turn my eye,
If I survey the ground I tread,
or gaze upon the sky.

There’s not a plant or flower below,
but makes Thy glories known,
And clouds arise, and tempests blow,
by order from Thy throne;
While all that borrows life from Thee
is ever in Thy care;
And everywhere that man can be,
Thou, God art present there.

(FURTHER updated) News from the Homefront

More pictures have been added, and further news is appended at bottom.
Well, I'm 3 minutes shy of putting in a SIXTEEN hour work day. I should be in bed, but I wanted to record that for posterity (hoping it won't happen too frequently!). It was worth it - enabled me to get all 2600 problems on the midterms I gave today graded. I don't feel so good right now, so I don't think I want to do this again any time soon.

On to the fun news! I have a new niece, Ava Marie Young. Congratulations, Mike and Amy on your 10 pound, 4 ounce bundle of joy. (Notice that Ava's initials spell out her mommy's name - how clever!). New life entering the world sure does put other stuff into perspective. What an amazing thing! I hope to get pictures of Ava posted soon!Things are crazy busy/crazy good for our family right now. Mike and Amy got keys to their house today, the day after Amy gave birth - what timing! They and we worked hard all summer to have our house hunt and move-in (sorry, I'm tired, probably don't make much sense right now!) happen DURING the summer - didn't work for either one. Amy will be moving in with a newborn, and I'll be moving in in the midst of a semester which is pushing me to 16 hour days! David and I sign our final paperwork tomorrow and get our keys October 1.

Thankfully it's all good stuff - good employment - new life - homes - may blessings!

Life keeps moving on. Anthony has a cross country meet tomorrow - another on Saturday - a fun, big invitational up in the foothills. Everything else has started up again too - church youth activities, Sunday School, piano lessons and so on.(Above are pictures from Wednesday's meet.)

And now - off to what sounds like the greatest blessing right now - BED!!! :-)
I'm updating this Friday. We found out today that our new house has been recorded and is in our name now. Today is also the day Mike and Amy took ownership of their house, AND someone Amy and I used to babysit when we were teens also got keys to her new house today! This must be contagious! What are the odds?

Dance and Drink and Sing

Continuing to think about the tree and all life and me, here is a poem by William Blake (1757-1827):
Little Fly,
Thy summer's play
My thoughtless hand
Has brush'd away.

Am not I
A fly like thee?
Or art not thou
A man like me?

For I dance
And drink & sing:
Till some blind hand
Shall brush my wing.

If thought is life
And strength & breath
And the want
Of thought is death;

Then am I
A happy fly,
If I live,
Or if I die.

A Hundred Years in Sun and Shadow

I put up the poem in my last post because of a sickening CRACK and sickening sight I experienced when I arrived on campus earlier this week. The sickening crack was of a giant piece of machinery coming down over the top of a tree that must have stood 100 years or more, that was torn, literally, limb from limb in 5 or fewer sweeps of the machine. As I witnessed this it really struck me that trees have no way to defend themselves or escape. I realize this is for a "good cause," our new science building which will house the Great Valley Museum, a planeterium, an observatory, and all our science classes among other things. But I really thought they would have saved these trees and incorporated them somehow, especially since this is a building dedicated to science, including life science, so this was quite a shocking sight to me.Here is the machine that tore a hundred+ year old tree down earlier this week. The claw just came down from on top and ripped into it.Above are similar but smaller trees in the same area. Below is the carnage.It was truly sickening to watch. Were this Berkeley and were I not tenure-track (i.e. not yet tenured), I probably would have stood in front of the tree to protect it! Phrases from Nemerov's poem (below) came to mind as I witnessed this horror:
"Maybe a hundred years in sun and shower dismantled in a morning . . . there it isn't on the ground . . . at dusk the darkening air . . . will be pierced by a bewilderment of birds."

A Bewilderment of Birds

They're taking down a tree at the front door,
The power saw is snarling at some nerves,
Whining at others. Now and then it grunts,
And sawdust falls like snow or a drift of seeds.
Rotten, they tell us, at the fork, and one
Big wind would bring it down. So what they do
They do, as usual, to do us good.
Whatever cannot carry its own weight
Has got to go, and so on; you expect
To hear them talking next about survival
And the values of a free society.
For in the explanations people give
On these occasions there is generally some
Mean-spirited moral point, and everyone
Privately wonders if his neighbors plan
To saw him up before he falls on them.

Maybe a hundred years in sun and shower
Dismantled in a morning and let down
Out of itself a finger at a time
And then an arm, and so down to the trunk,
Until there's nothing left to hold on to
Or snub the splintery holding rope around,
And where those big green divagations were
So loftily with shadows interleaved
The absent-minded blue rains in on us.
Now that they've got it sectioned on the ground

It looks as though somebody made a plain
Error in diagnosis, for the wood
Looks sweet and sound throughout. You couldn't know,
Of course, until you took it down. That's what
Experts are for, and these experts stand round
The giant pieces of tree as though expecting
An instruction booklet from the factory
Before they try to put it back together.

Anyhow, there it isn't, on the ground.
Next come the tractor and the crowbar crew
To extirpate what's left and fill the grave.
Maybe tomorrow grass seed will be sown.
There's some mean-spirited moral point in that
As well: you learn to bury your mistakes,
Though for a while at dusk the darkening air
Will be with many shadows interleaved,
And pierced with a bewilderment of birds.

New Season

Cross country has begun again and begun with a bang including not only the starter's gun but also the first thunder and lightning of the season! The first meet is always the big invitational, lots of fun!Above - chatting with team-mates before the race.
Below - warming up. Anthony (behind a green and yellow Davis guy) and the rest of his team at the starting line.A larger view of the starting line (love that tree!!).And they're off!Anthony had lots of family support! :-)Cheering him on to the finish! He achieved a personal best for this course - kinda cool for the first meet of the season.

Time and Connections

I just read a news item that the world's oldest person, Gertrude Baines, has died at age 115. It struck me for a number of reasons. My first best friend, Katie, was 75 years older than I. She lived to be 95, so I knew her for 20 years. She would have been 119 this year - only 4 years older than this woman; given that the oldest person on record was 122, Katie could have still been around. These women could have played together as kids!

I've always wished I had asked Katie more questions about her life. She was born in 1890 and was living in San Francisco during the great earthquake of 1906. Just thinking about these women amazes me with the connectedness we have with history if we listen to the stories our elders have to share.

Both of these women were born before there was such a thing as a world war

or a world series

or a car

or an airplane

or a TV

before we had visited the moon or had computers or hand-held calculators or highways. It seems more has changed more quickly in human history over that century than any other. How amazing to have lived that span of time! Both were middle-aged before World War II broke out. This leads me to the other thing that struck me. I've been feeling kind of old lately, but, wow, if this woman just passed away and was already middle-aged way back when World War II began, maybe I am still what Katie used to call a "spring chicken."

Do People Really Hate Math?

Well, it happened again. A "special" date popped up that caught people's attention, so I have emails in my inbox letting me know about it (which I love, by the way - keep 'em coming!).What strikes me as interesting is that so many people "hate" math, but yet so many people are intrigued by properties of numbers - or have lucky numbers - in some way have some affinity for number or pattern. I can't help but wonder if something we do in the schools, forcing some sort of performance anxiety or something, is what turns people off to math and causes them to hate it. It's been my experience that people actually like number puzzles and patterns, even if they claim to hate math. If this wasn't the case I wouldn't get so many emails about things like this with the subject line, "Check this out! Really cool!"

Today is "special" because it is (to write it one way) 9/9/9.

If you're interested in more about this day and the number 9, click on this link. Different cultures have different meanings associated with different numbers. In many countries 7 is considered a lucky number, and 13 is considered unlucky (to the point where some tall buildings have a 12th floor and a 14th floor but no 13th floor in between). In China 8 is considered particularly lucky because the word "eight" in Chinese sounds like the word for wealth. Remember last year, the Olympic Games were opened in China at 8pm on 8/8/8.

What follows is a little math paradox for you on this "special" day.

Numbers have a variety of properties assoctiated with them. There are all sorts of numbers. They can be odd, even, prime, square, triangular; there are even perfect numbers, amicable numbers, narcissistic numbers and schizophrenic numbers and many, many other types.

For example, six is a perfect number because all the whole numbers below it that divide into it also add up to it: 1+2+3=6. Six is the smallest perfect number, so it is an "interesting number" (or so some would say :-).

Here's the paradox. If we try to separate numbers into those that are "interesting" and those that are "un-interesting," we find that all numbers are interesting. If we begin at 1 and work our way up, noting the interesting properties of each number, when we came across the first one that was "un-interesting," it would be interesting BECAUSE it was the first un-interesting number - and so on. So, all numbers are interesting!

Maybe?

After all my earlier enthusiastic posts about houses we've looked at - and then having lost the bids - I've learned to be a bit more restrained about this topic, but we just got a call from our realtor that it is most likely that this one is going through. The sellers have accepted our post-appraisal bid, so now it's just inspections and escrow and so on. I don't dare say it's a sure thing yet, but I am going to go ahead and dare to post at least a few pictures. I'm too excited not to.The current owners have such a wonderful sense of taste and have kept up the house and yard so well. I'd love to move in and be able to keep the decor that is there now!

If this does work out, the next challenge is going to be how to take on the task of moving in the midst of a new semester that is EXTREMELY busy for us all - far more busy than our usual busy semesters. I guess we'll figure it out - clearly other people do!
