Dusty Cardboard Box
I came across a booklet that I made for a second-grade assignment. It was supposed to be about yourself, your family, etc. One of the questions was, what would you like to be when you grow up? My answer, in 7-year old's scrawl, was "I want to be an airplane pilot."
Until seeing that book, I didn't realize that my dream extended back that far. Early in life I was obsessed with trains, and there was a good half-box of crude train drawings to prove it. I'm not sure why my interest switched to planes, since in second grade I had never flown. I actually didn't fly until I was 11 years old, at which point interest became addiction. I've never lost my love of flight since, and I hope I never do.
