Do you hate how young people swear?

[.]

It's one of my biggest pet peeves. I'm in 10th grade, and besides the occassional "f*ck" or "sh*t", my friends and I rarely curse. I have class with this 9th grader and he swears all the time. I've put up with it for like 2 months, but in like the last week I can't take it anymore. He thinks he's really sarcastic and sounds cool, he sounds like a moron. Every time he curses, I repeat whatever he says in a very monotonous, serious tone. I think he's getting the point of how utterly stupid he sounds. I don't care at this point if this kid hates my guts...I'm not listening to him and his crap all year long.
