Dear younger brother,
I’m writing to discuss with you the problem of bringing mobile phone along to school. I think it’s very common for young people to have a mobile phone nowadays for the life has been improved a lot, but many students cannot have used it in a proper way and it often interrupts the class and even affects their studies. As a middle school student, we don’t have to get in touch with others during our studies. I hope you can draw some useful lessons from other’s failing. You had better not bring your mobile phone along when you go to school.
Love,
Li Dong
