Whatever...

You phone for your mom to come pick you up from school. You wait for about 20 minutes and she still hasn't shown up. You are waiting in front of the school when this annoying kid from your biology class comes up to you and begins to chat about the latest homework assignment. You act disinterested but he doesn't seem to be taking the hint. All you want to do is go home and eat a fluffernutter sandwich. The kid is still droning on. What do you do to escape?!
