What do you think of my art teacher?

So im in the 8th grade and i always get A's and teachers love me. Well this year in my art cl my teacher is honestly being rude and just horrible. I tend to talk alot and i know that isn't good but she still doesn't have the right to be so rude. She also tells me i swear alot, which i do but i don't say anything rude or mean about anyone and always tell her im sorry. AND she swears too. She will say to my cl "Now kids, I don't like to be a bitchy teacher but ....". I mean come on, im in the 8th grade, we all swear, so deal with it. And listen to this. So we made these paper mache monsters and then we finished them and had an open house. I was really excited to show my parents my monster, but it turns out my wasn't on desplay. I figured the teacher just forgot so i left and went somewhere else in the school. The next day in that cl my friend, who the teacher is also rude to and didnt put her monster out, goes " ms.p, why wasnt my monster at open house last night" then she rudely said " WELL i dont mean to be insulting but i honestly think that some of them were not 8th grade quality and shouldnt of been shown" then she looked at me and my friends and gave us all this look. i was honestly very angry and insulted, but i didn't want to get in trouble so i just left it at that. then a minute later she came up to me and said " yea know, you are using the wrong paper that paper is too thick. you never asked me if you could use that paper, im very upset" and i told her i was sorry and didnt realize. she just gave me an attitude and said " and throw the gum away" I WASNT CHEWING GUM IT WAS COUGH DROP AND I WAS COUGHING AND SICK. the only reason i went to school was that so i could catch up on art work! i said " its a cough drop" and she said " well i dont seee a note so spit it out." i honestly just think she is rude! I know this is a loooong thing but if you have the time read it and let me know what you thing. thanks in advance <3 :)
