補習-The Flea and the Man

A MAN, very much annoyed with a Flea, caught him at last, and
said, Who are you who dare to feed on my limbs, and to cost me
so much trouble in catching you?' The Flea replied, O my dear
sir, pray spare my life, and destroy me not, for I cannot
possibly do you much harm. The Man, laughing, replied, Now you
shall certainly die by mine own hands, for no evil, whether it be
small or large, ought to be tolerated.
