Kids know they can't make it alone, yet at the same time, built into each one of us, is a survival ethic. It says, "Nobody cares and you have to look out for yourself and if you don't, you'll die." These two things work against each other. I think most kids are very frightened of their parents, and that's what all fairy tales reflect: Parents will fail you and you'll be left on your own. But, of course, everything comes out right in the end and the parents take you back.
