sorry if I posted this in the wrong section. in my dojo the higher ranking children (under 16) are allowed to attend the adult class. while I have no objections to this, there is this one kid I'm often paired up with for sparring, self defense, etc. the problem is, he acts like he's 5 which causes problems, he flinches and starts wimpering even before any excersises begin, and goofs off during sparring. my kyoshi, sensei and rest of the senior belts know he does this, but I'm still paired with him--we're about the same height. any advice?
