THEY MAKE FUN OF ME FOR MY BUTTCRACK

I'm excited for my first day at college, but the kids behind me keep laughing, they're rich kids who want to humiliate me, I turn around and ask them what's so funny... They keep asking me if it's breezy and if I'm cold or if I'm crazy, I hate having people close to me who want to bother me with their laughter, I explain to them that it's really hot and show them the sweat on my head, how could it be windy in a heat wave... I lean over and open the classroom window and sit back down and they keep saying that I'm making them laugh, have an awesome Christmas... They ask me if my jeans are small, I obviously explain that they fit me perfectly and then they say that it's a nice crack...
