my friend is 13 and he is always moving about i have never seen him not wonder about in a lesson in the 4years i have known him. PE is his top subject but he is easly bored when waiting for his turn and this tends to leave him really irritated or some times he just gets up and does some random backflips and cartwheals. in lessons he is missbehaving alot and when he gets in trouble it is the most amusing thing ever he will do walkovers out of the class room while swearing at the teacher. so basicly he is hyper and easily bored. is he just an attention seeker like most teachers say or do you think he has ADHD???
