The Bat and the Weasels
A bat fell upon the ground and was caught by a Weasel. The bat pleaded with the weasel to spare him his life. The Weasel refused, saying, “I am by nature the enemy of all birds.” The Bat assured him that he was not a bird, but a mouse, and thus was set free.
Shortly afterwards the Bat again fell to the ground and was caught by another Weasel. The bat begged this weasel not to eat him. The Weasel said “I have a special hostility to mice.” The Bat assured him that he was not a mouse, but a bat, and thus escaped the second time.
Moral: It is wise to turn the circumstances to your advantage.
