Tip - Never Put His Mother Down

In most cases, sons are closer to their mothers and will not tolerate any criticism towards them. My girlfriend actually has a lot of similarities with my mother and she still use to put my mother down, i hated it.  Our biggest fight happened because i did not say anything for years and my girlfriend kept doing it.  One day i could not take it any more and you can guess what happened.... the end result "she never did it again".

Even when he criticizes his own mother, don't pitch in.
