he's changing his story? i'm pretty sure you have never talked to him so how do you know what his story is? and his head hurt cause thats what hit you in the face, not his fist. he flipped you? it sure looked to me like you hit him then fell strait down. i sure didn't see anyone flip. he went into a football stance which drops his head to your heads level, because that is just his instinct from football. and here is something to think about when a car hits a brick wall in a wreck does the wall get hurt or does the car? oh and for you independence people the answer is the car.
