Once there were two Cocks living in the same farmyard who could not bear the sight of each other. One evening he was walking along the open road outside the village. The next day, dressed in the skin, the Wolf strolled into the pasture with the Sheep. The foolish bird got the idea that if he lived like the Swan, swimming and diving all day long and eating the weeds and plants that grow in the water, his feathers would turn white like the Swan's. Besides, I did not know the Cranes were going to steal. I should be glad to do as you ask, he added, but I have noticed that there are many footprints leading into your cave and none coming out. Then handing the bundle to each of his Sons in turn he told them to try to break it. I dislike causing sorrow to anybody, and I am sure I can soon gnaw this string to pieces. But after the wedding, when the Kite flew away to find something to eat for his bride, all he had when he returned, was a tiny Mouse. Not one escaped the teeth of the hungry Weasels.
Those who seek to harm others often come to harm themselves through their own deceit.
