About ten years ago when I was an undergraduate in college. I was working as a practice student at my University's Museum of Natural History. One day while working at the cash register in the gift shop, I saw an elderly couple come in with a little girl in a wheelchair.
As I looked closer at this girl, I saw that she was kind of set on her chair. I then realized she had no arms or legs, just a head, neck and main body. She was wearing a little white dress with red dots.
As the couple wheeled her up to me, I was looking down at the register. I turned my head toward the girl and gave her a wink(眨眼). As I took the money from her grandparents, I looked back at the girl, who was giving me the cutest(可爱的), largest smile I have ever seen.
All of a sudden her handicap (残疾)was gone and all I saw was this beautiful girl, whose smile just melted me and  gave me a completely new sense of what life is all about. She took me from a poor, unhappy college student and brought me into her world--- a world of smiles, love and warmth.
That was ten years ago. I'm a successful business person now and whenever I feel down and think about the troubles of the world, I think about that little girl and the remarkable lesson about life that she taught me.
