I very rarely leave anything behind. I've been out of school for years now but I still clearly remember only leaving one item in my locker, and that was my Algebra II book at the end of the year. Obviously I didn't need it anymore.

I've always been like that though. I almost never lose track of things, no matter how cluttered my room gets or how much of a rush I'm in. Partly because I hate misplacing items but mostly because I'd have to replace the lost item myself. Nothing motivates personal responsibility quite like having to own up to the consequences yourself.
