     When I was 16 years ago a boy gave me an important gift. It was a smile. It was the early autumn of my

first year at a junior high school, and my old school was far away. As a result, no one knew who I was. I was

very lonely, and afraid to make friends with anyone.

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

with my problems. And I didn't want my parents to worry about me. Then one day, my classmates talked

happily with their friends, but I sat at my desk unhappily as usual. At that moment, a boy entered the classroom.

I didn't know who he was. He passed me and then turned back. He looked at me, without a word, a smile.

     Suddenly, I felt the touch of something bright and friendly. It made me feel happy, lively 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 smiled, but he couldn't remember smiling at me!

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