Hahaha...
I did have a teacher who was pretty mean and stupid.
One girl (a couple years older than me) struggled a lot with this teacher. She was left-handed, but the teacher forced her to write and sign right-handed. After this went on for a few weeks, she complained to her mom... who was also an interpreter in that same school. Her mom scolded this teacher and it never happened again.
This same teacher made us deaf students listen to a tape recording of a man talking. There were also sounds of other people talking in the background on the recording. She expected us to listen and write down what the man said. She would rate us on our listening skills for no good reason.
She even forced her class to eat some asparagus and said that if we didn't eat it all, she would give us a low grade. Well, I got a low grade.
