How much I hate it when people mock you

How much I hate it when people mock you Literally, I can't stand anymore people who think they're funny by mocking you, especially if that is their response to an argument. Like yesterday I was at school and I was arguing with this guy, I blocked at a word and he started like "A..a...a...". You fucking arent funny, you just proved yourself you're a stupid ass monkey and that you couldn't find a better answer. Is there anyone with the same problem?
