How long has it been since my grandpa died?
He was a mathematician.
He was not famous but he loved math.
Every night he would go to bed thinking about math, and wouldsolvethe problems in his dreams.
We would spend time together every day, and you'd give meyouroriginal puzzles.
My family has kept his room untouched, even now.
We don't know math, but there have been many puzzles set intothisroom.
They are precious to us, because we think they might reveal hislastwill and testament.
I decided to go into his room because I wanted to be reminded ofhimafter such a long time.
