A mouse and a frog were friends. Every morning the frog would hop 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 by noon. The mouse who was delighted in his friend’s company, was unaware that his friend, the frog, was slowly turning into an enemy. The reason?The frog felt slighted because though he visited the mouse everyday, while the mouse on his part, had never made an attempt to visit him.
One day, the frog felt he had been humiliated enough. When it was time for him to take leave, he tied one end of a string around his own leg, and tied the other end to the mouse’s tail. Then he hopped away, dragging the helpless mouse behind him.
The frog dived deep into the pond. The mouse tried to free himself but could not, and soon was drowned. His bloated body floated to the top.
A hawk saw the mouse floating on the pond’s surface. He swooped down, and grabbing the mouse in his talons, flew to the branch of a nearby tree. The frog, of course, was hauled out of the water too. He desperately tried to free himself, but couldn’t and the hawk soon put an end to his struggles.
In Africa, there is a saying: "Don’t dig too deep a pit for your enemy. You may fall into it yourself".
