Why can't those boys...

I caught myself saying "why can't those boys..." then I realized I think this a lot during the day. "why can't those boys shut the door when it's freezing cold outside?", "Why can't those boys shut the cupboard door?", "Why can't those boys just sit down on the couch instead of flop down?", "Why can't those boys put the toilet seat down in the middle of the night?"," Why can't those boys replace the toilet paper?", "Why can't those boys put the milk away after getting a glass?", And why do those boys... "Why do they use 5 million pots and pans to cook something as simple as spaghetti?", "Why do they make such a mess?, "Why do they smell so bad?"... I guess the answer to the question I've been asking all my life is simple... It's because they are BOYS!
