In ancient China, the people desired security from the barbaric hordes to the north; so they built the great Chinese wall. It was so high they knew no one could climb over it and so thick that nothing could break it down. They settled back to enjoy their security. During the first hundred years of the wall's existence, China was invaded three times. Not once did the barbaric hordes break down the wall or climb over the top. Each time they bribed a gatekeeper and then marched right through the gates. The Chinese were so busy relying upon the walls of stone that they forgot to teach integrity to their children.
