Hmm, I was talking about raising kids and teaching them disciplin, morals and how to behave, your wife and boss should know that already.
My parents stopped smacking me when I grew older because at that point they could just as well talk to me, their authority was established and I became more reasonable.
Smacking the wife is about as bad as wives smacking the husband or boyfriend, which can often be seen in movies and is surprisingly not frowned upon. It's always the fault of the man.
