Dear Jim,

     I'm glad to have received the letter you sent me last week.

     As to your question in your letter, I'd like to tell you it's very common for us students of middle school. I suffered from the same problem  at one time. Therefore, you don't have to worry about it too much. If

you want to make a difference, you can do the following things :

     Most important of all, you should try to communicate more with your friends and teachers actively to

throw light on what you think of. .Only in the way can your friends understand you more. And you can talk about what others care about and the things and persons they are interested in. Besides, helping others is

of great importance for you, for others can be kind to you if you are friendly to them.

     Best wishes to you !

                                                                                               Yours faithfully,

                                                                                                   Li Hua
