Teacher accused me of stuttering on purpose?????

Teacher accused me of stuttering on purpose????? Some weeks ago I was talking with my friends about our old teacher. She was a shitty teacher and nobody liked her, so we were basically trashing her. At one point a friend of mine says: "Do you remember when she accused you of stuttering on purpose?" "... what...?" "It was during distance learning. She thought you were doing it to avoid answering her question." "Oh, that. Yeah that's right." So I completely forgot that this thing happened! I even though my friend was making that up, but everyone else also remembered that, so I'm just bad at remembering rude people apparently. I think it's pretty fucked up because I was answering a question IN LATIN, in a meet video call, during an interrogation. That teacher knew I had a stutter and she even heard me stutter before in real life. Honestly I feel bad for not telling anyone at the time. I think even telling my parents what a bitch she was would have changed something, maybe I could have even gotten an apology but I doubt of that, considering I never heard her sincerely apologise to anyone.
