A man was annoyed with a flea that was flying around the top of his head and crawling on his skin. The man finally caught the flea and yelled, “who do you think you are, that you might cause me so much trouble?” The flea replied, “Don’t be rash sir! I can’t possibly do you too much harm.” The man laughed and replied, “It is only fair that I destroy you for no evil, large or small, should be tolerated.”
