When I was a sophomore at Acadiana, a teacher that could never control our class blurted out, "Do you act like this in Mr. X's class?!". One of my buddies goes, "No, but we respect him.". She started to cry. After that episode our class actually started trying to help her teach her class. I actually liked her, but she was never capable of commanding a class of HS sophomores.
