Sometimes when me and my friends are just going somewhere on campus and its really quiet I just start hysterically laughing because my mind started drifting and they all look at me like I'm about to set them all on fire and run around naked. Or sometimes in the same scenario I start yelling curse words because I just remembered something I did as a kid that was incredibly stupid and there's no crescendo leading up to it. It's just sudden and random. Also, sometimes for some reason I just pick someone out at a crowd and just stare. I think I zone out at these times but I just....stare. As one of my friends put it, "You are the incarnation of insanity."
