It is now common knowledge that when girls have a problem they wax eloquent about it in a bid to find relief, while boys just prefer to keep mum and handle it all themselves.

This interesting attitude difference between the way boys and girls handle problems could well have begun in childhood itself. While girls may feel that talking out their problems brings relief and maybe even a solution, boys just see no point in talking their problems out. Infact, going a step further, men feel that talking unnecessarily might take their focus away from the problem, and hence they consider it a waste of time.
