The difference between a man and a boy. Also, Bush thought he was infallible like a god. In the end, we all paid for the idiot child's mistakes over and over while he never learned one lesson.
But don't expect the Republicans to learn from this. They will be as childish and money-driven and fear-based as ever.
NOTE: At 1:26 Bush says "disappointments rather than errors" then rubs his neck. Classic textbook body language for trying to deceive.
