“It's been said that adults spend the first two years of their children's lives trying to make them walk and talk, and the next sixteen years trying to get them to sit down and shut up.
It's the same way with potty training: Most adults spend the first few years of a child's life cheerfully discussing pee and poopies, and how important it is to learn to put your pee-pee and poo-poo in the potty like big people do.
But once children have mastered the art of toilet training, they are immeadiately forbidden to ever talk about poop, pee, toilets and other bathroom-related subjects again. Such things are now considered rude and vulgar, and are no longer rewarded with praise and cookies and juice boxes.
One day you're a superstar because you pooped in the toilet like a big boy, and the next day you're sitting in the principal's office because you said the word "poopy" in American History class (which, if you ask me, is the perfect place to say that word).”
