About 10 years ago when I was a student in college, I was working in a shop near my school. One day, I saw an elderly couple come in with a little girl in a wheelchair(轮椅).

As I looked at this girl, I saw that she was seated in her chair. I realized she had no arms or legs, just a head, neck and body. She was wearing a little white dress with red dots(圆点).

As the couple wheeled her up to me, I was looking down at the cash register(收银处). I turned my head toward the girl and gave her a wink(眨眼). As I took the money from her grandparents, the girl gave me the biggest smile I have ever seen. All of a sudden her disability disappeared. All I saw was this beautiful girl, whose smile gave me a new sense of life. She took me from being a poor, unhappy college student and brought me into her world of smiles, love and warmth.

That was 10 years ago. I’m a successful businessman now. Whenever I am down and thinking about the troubles of the world, I think about that little girl’s smile and the life lesson she taught me.
