You must be very busy these days. I called you several times, 1 no one answered. Are you still busy 2 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 3 I have few friends. Last month, some of my classmates 4 me to the Internet café after school. It was a lot of fun 5 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 6 than ever before, and Mom found out the reason. She got really angry with 7 ! She wouldn't even let me go out with my friends again, so I had to 8 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 9 , so I went to the Internet café 10 them like before. Mom is really disappointed with me now. I didn't mean 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 |
