When guys first start they feel the need to "win" in sparring aka break a bone, knock you out, put you on the mat. As they gain more experience and realize what sparring is used for they stop acting like nobs.
I paid him back but still feel pissed off with him and won't be sparring with him again, I don't trust myself. Coming out guns blazing in sparring is out of order IMO. My fault for being lax also.
