ways to irritate me

Cheat in my class.

While I'm standing two feet away from you.

Pretend you were "only joking" about the cheating.

Argue that since you hadn't actually turned the assignment in yet, it's really not cheating.

Throw a fit when I give you and the friend who was cheating with you a zero on the assignment anyway.

Glare at me all class. (Okay, so maybe I found this part slightly amusing. Because if you think that I'm concerned whether or not you like me, you are WRONG. So it's pretty funny watching you try to annoy me.)
