It was a cold winter night. I hurried to go home from work on my motorbike.

While I was waiting for the green light, I saw an old man toward me. He stopped me and said , "Excuse me, could you please help me?" I looked at him up and down. He looked about 70 years old. The old man took out a 10-yuan bill(钞票) and said to me, "You see the old lady over there? She's selling baked(烤) potatoes could you just take the money and buy one from her?" He pointed at an old lady selling something about fifty meters away in the corner.

"But why don't you go and buy it ?" I was puzzled. The old man continued. "That old lady is my wife, and it's her day to sell baked potatoes. Just now I called her. She told me that there was only one sweet potato left and she wouldn't go home until all the sweet potatoes were . But I know she can't stand the cold because her legs hurt. I'm very about her." At that time, I understood why the old man asked me to buy his potato. I felt really warm and moved. Without taking the money, I rode to the old lady quickly and bought the last one. As I said goodbye to the old man，I could see him standing there with a smile.
