     Sixteen years ago a boy gave me an important gift. It was a smile.

     It was the early autumn of my first year at a middle school, and my old school was far away. As a

result, no one knew who I was. I was very lonely, and afraid to speak to anyone.

     Every time I heard the other students talking and laughing, I felt my heart break. I couldn't talk with

anyone about my problems.

     Then one day, when my classmates were talking happily with their friends, I was sitting at my desk

unhappily as usual. At that moment, a boy entered the classroom. I didn't know who he was. He passed

by me and then turned back. He looked at me, with a smile.

     Suddenly, I felt the touch of something bright and friendly. It made me feel happy and warm. That

smile changed my life. I started to talk with other students and made friends. Day by day, I became closer

to everyone in my class. The boy with the lucky smile has become my best friend now.

     One day I asked him why he had smiled, but he couldn't remember doing so!

     It doesn't matter because all the dark days have gone. I believe that the world is what you think it is.

If you think it is lonely, you might always be alone. So smile at the world and it will smile back.
