I found a box in the garage while we were moving (actually, I kew it was there all along) that belonged to my grandfather, which I took for my own after he died. In it I put all of those things that I held precious during my teen years living at home.

Assuming you had a box that contained a volume of 6×3x9 inches, what would you put inside it that would represent the most significant things about your life that you would want to remember?
