Whenever I leave something in my apartment and have to go back up, I always end up realizing I forgot something even more important. Like last night I was half way out the door and realized I forgot something. Went back inside and realized I forgot to close my window. Then on my way out, ran into my hot next door neighbor with is girlfriend. He told me that the guys downstairs play Guitar Hero. So that was sort of critical information that I've been wondering forever.
