Don't hit a woman. Don't hit a man
I've heard about a curious case some years ago. A couple decided to divorce as a husband... was beaten by his wife... this case could be very funny if not so sad. This kind of a family relationship is normal in exactly this family. Perhaps, they find some kind of relaxation and pleasure in it. The last thing they want is help. The matter is that in some families it is a usual way to "communicate". Many cases are solved right at the place without the interfering of the policemen or other people.
There is an opposite case. A had a friend who became really anger about a wife's work, but at the same time he wanted her to work and earn money for the family business. Longer time at work was accepted as his personal offense and was hardly punished. No warm word, no apologies after that. Was it really a good way of a family relation? Was it comfortable for both of them? No, every of them was suffering because of the different expectations. At least they gave up the opportunities to safe their marriage.
Anyway, the family articles make a woman be sure that hitting is non-normal in the relationship. Who knows, today he hits her for too hot soup. Another day a woman will be hit longer and crueler.
As for me, fighting in a family can not be a normal way of conduct as it discovers the negative sides of a human character and personal feeling of family life dissatisfaction. For what is a family life which is not cozy, tender and supportive?
