Is it normal to tell people to shut up or stop for some reason?
I have this person in my class that if I am talking to a friend, he'll turn around and give me a nasty face and say "Just shut up".
I'll say a joke to a friend or randomly because I remember it, and of course, it's funny and he'll respond with "Oh my god just shut up."
I once tied my shoe and he looked behind and like every time, gave me the nasty "Smells like fish/I don't like your face" look and said "Every time I turn around it's your ugly face, it's you, just go."
And of course he tells me this, to shut up, my ugly face, and more.
Now, I have not had any physical fights with him, nor verbally, I have not affected him, I just sit behind him in class and have not done anything to him.
