　 Everyone had their friends, but I knew one girl who didn’t. I guess you could call her a geek, because all she did was read, study, and do homework. I don’t think she even played a sport. She was one of those quiet people who no one really paid attention to, and those who was often laughed at. I had heard all kinds of rumors (谣言) that she had problems, but I didn’t really believe them.

　 My friends and I were nice to her. We let her sit at our lunch table and we often said “Hi” to her, but she wasn’t our best friend. Throughout the year, she started talking to us more and more. We continued being kind to her. She was normal as far as I was concerned (就我而言). She was just really quiet.

　 During the summer holidays I got a letter from her. It read, “I just wanted to thank you so much for being so extremely kind and friendly to me this year. Before you became my friend, I had no one to talk to or sit with at lunch. I didn’t think anyone wanted me around. I even wanted to kill myself because of this. But you and your friends changed that. You made me feel wanted. It meant so much to me. I am going to be moving and going to another school next year. I’ll never forget you and what you did.”

　 By the time I finished the letter, I was in shock. I could not believe what I had just read. I learned that the simplest things and the smallest acts of kindness can mean the world to someone else.
