A farmer's dog, Dolly, had puppies(小狗), and the farmer needed to sell them. He painted a sign and put it in his yard. As he was putting up the sign, a little boy walked up to him.
"Sir," he said," I want to buy one of your dogs."
"Well," said the farmer, "these dogs are very expensive."
"Can Ijust look?" asked the boy.
"Sure," said the farmer and whistled(吹口哨). "Here, Dolly!" he called.
Dolly ran out from the doghouse and four little dogs followed her. The boy became excited. Then, the little boy noticed another dog. This one was smaller. It moved slowly and tried to catch up with the others
"I want that one," the little boy said, pointing to the little dog.
The farmer said, "Son, you don't want that dog. He will never be able to run and play with you like these other dogs."
The little boy reached down and rolled up(卷起)one leg of his trousers. He showed a cast(石膏) on his leg and a specially made shoe. He said, "You see, sir, I don't run too well myself, and he will need someone who understands."
The world is full of people who need someone who understands.
