"I don't like your attitude."

What I should have said:
"And I don't like having to re-do a now meaningless assignment when my original is perfectly acceptable. I devote an inordinate amount of time to this class as it is. Remember, you need me in this class more than I need this class. I could easily drop tonight and fuck up your stupid 'content expert' scheme!"

What I said:
"Well, I don't like YOUR attitude!"
