A man had a little dog， and he liked it a lot． He would pat （拍） its head， put it on his knee and talk to it． Then he would give it some food from his own plate．

A donkey looked in through the window and saw the man and the dog．

"Why doesn't he choose me as his pet？" said the donkey． "It is not fair． I work hard， but the dog only shakes its tail， barks and jumps onto the master's knee． It is not fair．"

Then the donkey said to himself， "If I do what the dog does， the master may choose me as his pet．" So the donkey ran into the room． He brayed （嘶叫） at the top of his voice． He shook his tail so hard that he knocked over a jar on the table． Then he tried to jump onto the master's knee．The master thought the donkey was maniacal ， and he shouted， "Help! Help! " Some men came running in with sticks in their hands and they beat the donkey until he ran out of the house．

"I only did what the dog did，" said the donkey， "and yet they still regard the dog as their pet and they beat me with sticks． It is not fair． "
