Yeah, if your provoked wouldn't you want to hit the person back?
My b/f was a bit of a naughty boy a few months back and I took a swing for him, he didn't hit me back he just restrained me, but if your going to take a swing for someone then expect them to hit you back.
A female friend hit her boyfriend and he hit her back, she cried and cried and came running to me for the sympathy vote, she didn't get it infact she didn't like what I had to say about it either!
Alls fair in my opinion
