When I was in high school my math teacher asked me, "What happened to your nose?."
He was a nice guy, and I am not sure what compelled him to say such a jerk thing to a fifteen year old girl with an ugly nose. I said, "Nothing asshole!" and ran out of the class humiliated. I never went back to the class because I couldn't face him or the other kids who had heard. It was traumatic. He gave me a C, which I did not deserve because I never turned in another piece of work or took another test.
