There's always the option of not giving a shit about what he thinks, Nate. And remembering that he's got it in for you. And... wait... right... not letting him get to you. He's doing it on purpose, Nate. There's no basis for it. Tell him to take it up with Charles if he feels he's being persecuted. Let someone else mark his papers if necessary. Don't play the game. You're the teacher, he's the student. Walk away.

And don't get bitchy at me, you know you're just going to lose that one.
