I’m glad you reached peace with it but from my perspective, that teacher is a mega jerk.

One time I was day dreaming in class, I forget about what but 100% not aware of my surroundings, and the teacher stopped the lecture to ask me to “stop smiling at her like that it’s weird” in one of my highschool classes. It didn’t really ‘bother’ me but I did consider filing a complaint with the school lmao.
