I have been trying to get you to settle down in my class. You're an adult, start acting like one! You are going to respect me, I can't take this anymore. Since I cannot make you behave in class, maybe we need to take this somewhere else so you can learn. You were doing this for attention, you want it? FINE you got it! Maybe you needed to be punished, maybe that's not the best route. If I reward you when you behave will that help? I cannot have you undermining my authority and I do NOT want you in my class again next year. Maybe if we work something out I can get rid of you and you can learn to behave.
