SIXTEEN years ago a boy gave me a nice gift which 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 make friends with anyone.
Every time I heard the other students talking and laughing, I felt my heart broken. I couldn’t talk with anyone about my problems.
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, with 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.
