Lack of maturity and their mothers treated them like they are little princess (due to the paternalistic view that it is more desirable for a woman to have a son and thus a woman is considered worth more in society if she pops out boys, even though gender is determined by the father's swimming team), so some men turn out very narcissistic. They also tend to feel that the children steal their woman's attention away from them. Not all though. Some are wonderful fathers.
