There was once a man who had a donkey and a beautiful lapdog. The donkey was kept in a barn and had plenty of corn and hay to eat. Indeed, he was just as lucky as any donkey could be. The little dog stayed in the house and was well liked by the master. He was always playing and jumping about in an funny way and was allowed  to lie in his master’s lap(膝盖). Meanwhile, the donkey had plenty to do. He pulled wood all day long and had to take his turn at the mill during the night. He often complained about his problems, and it bored him to see the lapdog living such an easy life, while he had to work so hard. Finally he thought to himself that if he acted the same way as the lapdog to his master, he would be treated the same way. So, one day he ran out of his barn and went fast into the house, where he began to kick about in a very strange way. Then, swaying his tail and imitating the funny behavior of the pet lapdog, he knocked over the table where his master was eating. He also broke all the dishes into very small pieces and did not stop until he jumped onto his master, trying to lick and paw him with his rough feet.

Seeing their master in great danger, the servants thought it was time to help him. They beat the foolish donkey with sticks until he could not get up again. As he was about to die, he cried, “Why couldn’t I have remained satisfied the way I was? Why did I try to imitate a creature who was nothing but a lazy puppy after all?”
