What do I do about this horribly mean teacher?

I understand you I used 2 have a teacher like that last year and i pray 2 god that I don’t have her this year because she is so mean. Well what I did whenever she used 2 tell me mean things like that or offend me I would tell her something back that sounded pretty respectful in a way of it not sounding rude but sort of defending yourself. Ofcourse is not good 2 talk back 2 a teacher but sometimes u gotta step up in life for yourself because if u don’t noone else is I hate teachers like that one thing I remember I told my teacher was that I was dissapointed in her talkin 2 her student in such way being a teacher that I didn’t know teachers were like that I thought they could set up an example 4 their students and sh never said a word back 2 me. I think u should say somethin like that either privately or in class but please be careful make sure it sounds mature and true don’t get in trouble or another thing you could do is talk 2 your parents about it and make them talk 2 him they sort of chiken out when it comes 2 parents . And no that is not such way 2 talk 2 a student in fact I think that if anything Is herd by another staff or even the principal your teacher can get fired I hope my advice helped u in a way
