That sounds like a REALLY annoying teacher!I HATE my science teacher he is going to call my parents because he can't see my face on camera and I said "go-ahead" because I told my parents I'm not going to show my face they got mad what said whatever like at least I don't say here and then leave I stay for the whole class I pay attention and turn in my work on time what else do you need from me!!! All my other teachers are fine that they only see the top of my head because they know that i am a good student
