"CINDY DID SOLVE THIS PUZZLE" - David Leung

On this third September 11th remembrance, I wanted to include something positive and
upbeat to remember Cindy.  I'd like to thank Cindy's Columbia University friends David
Leung and Kevin for providing the puzzle solution.  I included some old email excerpts
from David so you could see how he knew Cindy.  Thanks David!

I got to know Cindy when she was working as the chemistry graduate student
coordinator at Columbia.  I should mention that she had been so helpful and that I would
not have been able to graduate without her, but I guess that is perhaps a bit too obvious
knowing Cindy.  Frankly, she was more like a friendly enemy to me.  We used to give
each other brainteasers and geometry problems; we had a lot of fun trying to drive each
other nuts--in a good way.  And as much as I want to deny, Cindy always finished the
New York Times crossword puzzles before I did.  I shall forever treasure the time and
brain damage we caused each other.  The brainteasers that Cindy and I gave each other
were all oral, face-to-face kind of challenges.  We enjoyed making fun of how long the
other person takes to solve a "trivial" question.  "Oh, come on, that's SO obvious!"  
"Oops, time's up, where is your solution??"

My guess is that you have experienced yourself and have heard from others Cindy's
magnetic personality, wonderful sense of humor, and tremendous brain power.  Perhaps,
and I am saying this only as a naive "outsider," we should all remember her lovely smile,
and above all, we should congratulate each other that we have the fortune to have Cindy
in our lives.  Would you rather not have known Cindy at all and therefore never lost her?  
Would I? Honestly, I am glad that I know Cindy.  Having known her for only a VERY
brief part of my life, Cindy had made a permanent mark in my memory.  So we had little
chats in many mornings over coffee, and we talked after work about life, art, and what
have you.  Little things.  Little things here and there but wonderful time.

My friend Kevin and I had a discussion with Cindy and concluded that it is impossible to
draw such a line and mathematically proved it.  So Cindy DID SOLVE this puzzle.  
Attached please find a brief version of the PROOF.
