Dear Peter,
Thanks for telling me about your problem. But I don’t think you’re right. Here are some suggestions for you.
Nowadays public phones can be found everywhere. If you have to make a phone call, you may use them. It’s true that mobile phones make it easier to
communicate with each other, surf the Internet and play games, but if you use
them too much, it surely is bad not only for your eyes but
also for your study. So you’d better give up the thought that you want them.
What’s more, work hard on your lessons and read more interesting books.
If you put your heart into study, I’m sure you will get more and more interested in it. Finally, have an honest talk with your parents to let them understand what you are going to do. I hope you will get on with your parents soon.
If you have more questions, please ask me.
Best wishes,
Yours
David
