Dear Joyce,
You must be very busy these days. I called you several times,    no one answered. Are you still busy      on the report?
I called you because I am having problems with Mom and my friends these days. You know, I am a shy person. That’s   I have few friends. Last month, some of my classmates me to the Internet café after school. It was a lot of fun we could play the latest online games there, and it was the first time that I felt I was not alone anymore. However, my grades were getting   than ever before, and Mom found out the reason. She got really angry with     ! She wouldn’t even let me go out with my friends again, so I had to     them that I couldn’t go out with them any more. My friends laughed at me and even called me a coward (胆小鬼). I couldn’t stand    , so I went to the Internet café    them like before. Mom is really disappointed with me now. I didn’t want to make her sad, but I still want to have my own friends. What should I do?
Last, Mom and I miss you a lot. We hope to hear from you soon.
Your brother
Ben
