     When I was 13 years old, 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 to

anyone about my problem, 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 and, without a word, smiled.

     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 the 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. Now I believe that the world is what you think it is.

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