Every child hits a stage where they're just an asshole. I don't think the vast world of science & technology could even begin to explain the reason why. It just happens. As a parent, you have to know how to deal with the messiness of childlike behavior without acting like one yourself.

If you want to dance around the house half-naked,
Man. Go for it.
