An old man lived alone in his old house. He hardly ever came out. He wouldn't communicate with others.
One day, a little boy selling magazines knocked at the man's door. The door slowly opened. "Uh, sir, would
you like to buy a magazine?" The old man just stared (盯着) at the boy. The boy saw lots of dog sculptures
(雕塑品)on the table. "Do you collect dogs?" the boy asked. "Yes, they are all my family." Hearing this, the
boy understood and felt sorry for him." I have a magazine here about dogs. It's perfect for you." The old man
was ready to close the door and said, "No, I don't need any magazines."
The boy suddenly had an idea. He had a dog sculpture, which did not mean much to him. After a while, the
boy returned with a box. The old man shouted this time,"I told you no magazines!" "I bring you a gift." The
boy opened the box and handed him the sculpture. The man got surprised because no one had given him a gift.
From that day on, the old man started coming out of his house. He and the boy became friends. The boy even
brought his pet dog to visit the old man every week.
