Man, I'm really going to go off on this kid I know that's annoying.
Uh, did you ever discuss your problems with the kid?
Just briefly.
You shouldn't set bad example to a kid. Try to talk to him or her one more time, maybe that person will be more susceptible.
Alright, I'll take what you said into consideration.
That's great. You will likely get your way more if you treat the kid with respect, and you aren't likely to get told off by the parents, either.
