Did/Do you hate your teachers?

There was only one teacher I outwardly disliked. She was my math teacher two years in a row and she was horrible at her job. She use to yell at me for not understanding her. And she always said "parallelllll" as if that made it more clear. It was a running joke with all her students to mimic her. My dad told her off one day and she got as little nicer to me but was still an all around bitch. She passed away a few years later and I remember feeling sad. She wasn't old and had young children still in school. She was a terrible math teacher but there were people who loved her. They just weren't her students.
