We pretend that we know our children, because it's easier than admitting the truth--from the minute that cord is cut, they are strangers. It's far easier to tell yourself your daughter is still a little girl than to see her in a bikini and realize she has the curves of a young woman; it's safer to say you're a good parent who has all the right conversations about drugs and sex than to acknowledge there are a thousand things she would never tell you.
