I leave little post-it notes to myself all the time*. And about half of them, by the time I get around to reading them, make absolutely no sense to me. I'm looking at one right now that says "hand brake." WTF? It's my handwriting, so I can't chalk it up to some deranged intruder. Thing is, one day a few years from now, I'll smack my forehead and say "oh, SHIT! The hand brake! Well, too late now..."
*Is that a gay thing to do?
