Ohhhhhh, PE class...
I had a teacher freshman year of high school who liked to single me out in front of the class because it really bothered me. The most embarrassing was having to do push-ups by myself in front of everyone because I was so nervous I couldn't hit the wiffle ball, or when he made me stand alone on one side of the volleyball net while he served the ball at me hard enough to knock me over to "help" me learn to play better. This poor man is dead now, God rest his soul, but I still can't say I ever liked him.
