I’ve had my fair share of teachers who, to say it nicely, I didn’t get along with. In hindsight however, teachers usually don’t mean to hurt students. There are definitely exceptions to this, but if you find that most teachers are out to get you, I would dare say that maybe you should be the one to switch your attitude.
As for personal stories, oh boy! I have archives of those! Volumes upon volumes. One particular incident that sticks out was actually in my last year of high school. So I had this policy that if teachers can chose favorites so can students. So by some classes I was a model A+ student, frequent participator, copious note taker… and by others I would fail my way through the year. My report cards are testimony to my attitude lol. So anyways there was this one teacher who was NOT a favorite. In the middle of they year she called me out and asked me. “Streekgeek, I heard from Mrs. Whatever that you participate in her class, and you actually are doing well. Do you think you would try a bit harder in my class. I’m sure you have alot of nice things to add that will enhance our class” So I promised her if that’s what she wants I would gladly acquiesce. This teacher was in middle of teaching maaseh beraishes and the foundations of emunah. So I took all my knowledge of the subject at hand (which is alot, as emuna was something I had struggled with prior to this class) and sort of messed up her whole lesson. After class she called me over again and said she would be happy if I wouldn’t spew my kefirus so the whole class wouldn’t get influenced. That really hurt. Especially since this teacher has never been particularly kind to me since the beginning of that year. I guess I’ll never know what she had against me. Thinking back, maybe it wasn’t baseless and irrational. But I’ll never know cuz there is no way I would ever ask.
