Gary and Gavin were twin brothers who worked in a store owned by their father. After the father had passed away, they took over the store. One day, Gary left the bill on the cash register (收银台), but when he returned, the money was gone.
Gary then asked his brother," did you see that twenty-dollar bill on the cash register?" Gavin said no. But Gary did not let it go and kept asking. That made Gavin very angry and they quarreled with one another. The quarrel divided the young men. Later, a wall was built in the center of the store. For twenty years, hostility (敌意) never ended.
One day, a strange man came to the store. He walked in and asked Gary, "How long have you been here?" Gary replied that he'd been there all his life. "Then you are the person I'm looking for," the man said. "Twenty years ago, I was totally broke and hungry. I entered this store from the back door and saw a twenty-dollar bill on the cash register. And I took it. All these years I haven't been able to forget that. I had to come back and apologize for that."
The stranger felt shocked when seeing tears well up in the eyes of the middle-aged man in front of him. "Would you please go next door and tell the same story to the man in the store?" Gary asked. Then something surprised the stranger even more-after hearing his story, the two middle-aged men hugged each other. After twenty years, the wall that separated them finally came down.
