    A mouse and a frog were friends. Every morning the frog would jump out of his pond and go to visit his friend who lived in a hole in the side of a tree. He would return home at noon. The mouse was happy to have his friend’s company(陪伴) but he didn’t realize(意识到)that his friend was slowly turning into an enemy. The reason is that the frog felt unfair because he visited the mouse every day but the mouse never visited him.

One day, the frog had an idea. When it was time for him to take leave of (辞别)the mouse, he tied one end of a string around his own leg, tied the other end to the mouse’ s tail, and went away with the mouse behind him. The frog dived deep into the pond. The mouse tried to free himself but couldn’t, and soon was dead in water.

A hawk saw the mouse floating on the ponds surface. He swooped down(俯冲), caught the mouse and flew to the branch of a nearby tree. The frog, of course was pulled out of the water too. He tried to free himself, but couldn’ t and became the hawk’s food soon.

In Africa, they have a saying: Don’t dig too deep a pit(深坑)for your enemy, because you may fall into it yourself.
