When I was a wee lad I used to come home battered and bruised. A girl around the same age as me was the aggressor. Now I never hit back because my mother told me it was wrong to hit a girl.
After this went on for a bit my mother told me it was OK for me to hit her but only if she hit me first. The out come of this was I no longer came home battered and bruised.
This is ok advise for a child but as a man if a woman slaps me I will turn around and walk away. Then call the police.
