hey grey i know that kid that loves to argue and wont hear you out for even a second pretty good. i used to be that kid once. i always thought i knew more than the trainers. i think the thing to do with a kid like that is to sit down and show them some tapes. this is so they can see for themselves with there own two eyes whats what. show them some tapes of joe louis knocking people out left and right and lets see them argue with that.
