When people are kids their parents teach them all sorts of stuff, some of it true and useful, some of it absurd hogwash (example of former: don't crap your pants; example of latter: Columbus discovered America). This is why puberty happens. The purpose of puberty is to shoot an innocent and gullible child full of nasty glandular secretions that manifest in the mind as confusion, in the innards as horniness, upon the skin as pimples, and on the tongue as cocksure venomous disbelief in every piece of information, true or false, gleaned from one's parents since infancy. The net result is a few years of familial hell culminating in the child's exodus from the parental nest, sooner or later followed by a peace treaty and the emergence of the postpubescent as an autonomous, free-thinking human being who knows that Columbus only trespassed on an island inhabited by our lost and distant Indian relatives, but who also knows not to crap his pants.
