Unity

A lunatic set a house on fire while the village was asleep.  The fire spread rapidly to other houses.  Each family frantically ran about, attempting to save their possessions.  A wise bystander remarked, "You are silly people.  Instead of trying to save your own possessions why don't you put out the fire so that it will not spread any further?"
MORAL: If each person is only interested in their personal welfare, the world will not endure.
