But when deciding whether to hit anyone back - no matter how justified or unjustified the first person was in hitting in the first place - depends upon whether you prefer to choose the high road - a peaceful solution such as Puternut suggested - or the low road - and ride it all the way down with the one who hit first.
I think Puternut's method is a valid choice, but it could also be seen as rewarding anti-social behavior. If a woman is so immature as to use violence on a man--admittedly violence that may little chance of causing any lasting physical harm--to get attention and is successful in getting attention that way, why would she not use that same method in future. Perhaps some men like that method of communication. The other choice that has been stated by others is to simply walk away from the relationship if there is one. There's no need to be need to be with a woman who hits to get attention or because she is upset by words unless you like that sort of thing. It is an equally high road.
