          A little boy selling magazines for school walked up to a house that people rarely visited. The

house was very old and ran down and the owner hardly ever came out. The boy's parents told him to

stay away from the house, a lot of other neighborhoods children were told the same from their parents.

          As he was ready to walk away, the door slowly opened. "What do you want?" the old man said.

 "Uh, sir, I am selling these magazines and I was wondering if you would like to buy one." The old man

stared at the boy. The boy could see inside the old man's house and saw that he had dog figurines (小雕像) on the fireplace mantle. "Do you collect dogs?" the little boy asked. "Yes, I have many collections

in my house, they are my family here. They are all I have." The boy then felt sorry for the man, as it

seemed that he was a very lonely soul. Then the old man was ready to close the door and said,"No,

boy, I don't need any magazines of any kind, now goodbye."

          The little boy was sad that he was not going to make his quota with the sale. He was also sad for

the old man being so alone in the big house. The boy went home and then had an idea. He knocked on

the door again and this time the old man came right to the door. "Boy, I thought I told you no magazines." "No, sir. But I want to give you a gift." The boy handed him the figurine and the man's face lit up. "It's a

Golden Retriever, and I have one at home, this is for you." The old man was simply stunned (受惊的);

no one had ever given him such a gift and shown him so much kindness.

         From that day on the old man started coming out of the house and acknowledging people. He

and the boy became friends. The boy even brought his dog to see the man weekly.
