There is a fable that a donkey went to a camel and said, "Uncle, we shall be friends, we shall go grazing together." The camel said, "Child, I enjoy my walks alone." Said the donkey, "I am most eager to accompany you, uncle." The good-natured camel consented to it, and they both went together. Long before the camel finished grazing the donkey had finished and was eager to express himself. He said, "Uncle, I would like to sing, if you don't mind." The camel said, "Do not do such a thing. It will be a terrible thing for both you and me. I have not yet finished my dinner." The donkey had no patience, he could not control his joy and began to sing.
