Nick and you have been best friends since 2nd grade. This is your last few months of senior year before you graduate and Nick is suddenly barely talking to you and he’s always in a bad mood. He gets mad whenever you talk to him for a long time, even though you guys used to talk for hours without getting annoyed. One day you walk over and sit next to him during lunch and he completely ignores you. You try to talk to him but he just gets up and walks away.
