Dear Tom
I am very glad to be your deskmate.But I am very sorry to tell you that you often break our school rules.I think it's not right to speak loudly in class,eat or listen to MP3 when we are having class.Beijing a student,we should listen to our teacher carefully in class so that we can gain more.It's wrong to disturb others.Hope you will give up your bad habits and to to a good student.
Yours
Jim
