You pretend until pretending becomes a prison. Until you start believing in your own pretend games. Grown ups have become convinced that something terrible will happen if they ever admit that they are just pretending that they don't have all the answers. You see, kids know that are pretending.

Kid's know that they don't have all the answers. Kids play and pretend in perfect freedom, cause they know they are allowed. They have permission to be silly. They can make mistakes. They can be wrong.
