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 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 came into the classroom. I didn't know who he was. He passed me and then turned back. He looked at me, without a word, only 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 make friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile becomes 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 you are unhappy, you might truly unhappy. So smile at the world and it will smile back.
