I have only punched a woman once. My friend"s girlfriend (now wife), who I"ve also been friends with since high school, likes to piss me off. I like to piss her off too. It"s mutual. Either way one day I said something that was even more offensive than usual. I don"t remember what. She wound up and punch me as hard as she could when I turned away, around the shoulder blade. She"s pretty strong for a chick, played sports and all that. So I turned around and punched her right back in the shoulder. Nowhere near as hard as I can, and not nearly as hard as she hit me.
Naturally she freaked out, turned to her boyfriend and demanded that he do something about it. He laughed and told her that she shouldn"t dish it out if she couldn"t take it. She stormed off. We resumed drinking beer. The end.
She still brings it up every now and then. Cited it as a reason why she"d never introduce me to one of her friends, because I "beat women." I don"t much care, her only two friends are fucking hosebeasts.
