I'm going to tell my art teacher to shut the f**k up.
Are you kidding? Why are you going to swear at your art teacher?
He just told me something that made me really pissed off
Teachers can really tick you off at times, but this cursing is not the right thing to do. That could get you in big trouble. Accept the hardship and take a good look at yourself to see why you are really so angry and at whom.
No, I'm going to go aggro on him tomorrow.
I would recommend against being rude to and swearing at your teacher, even though he did something to anger you. You should be respectful of your teachers. If you think what he did was really terrible, then it might be best to bring it up to another teacher or guidance counsellor, since they'll be able to help you out.
