Baby Boy

I'm just wondering... When a man gets married to a woman and both decide to have a baby, The man always wants to have a baby boy. And If his wife brings a baby girl, he'll be really mad and sometimes making the whole thing sounds like its his wife's fault. This is really ridiculous coz I don't know why men are thinking that way when they're married. That makes them sounds like they still have some bonds with their Cavemen ancestors many years ago or something like that. The Men should break such bond and try to use their minds wisely just to know that having a baby is really wonderful thing and it doesn't really make a big difference if the baby is a boy or girl. Besides, Many Girls are much prettier and smarter than boys these days. :)
