Dear Tom
You told me that you spent over an hour to chat with people on line every day.I know that it is mysterious to talk to someone you never meet,and it will also be interesting.But if you spent too much time on it,you may lose your enthusiasm to make friends in really world.And you may not know how to get alone with people around you,like your family,your classmates and so on.Because making friends on line is really different from making friends in really world.And sometimes it might be not so safe.I really hope that you can go out with people around you more often,but not people on line.
Your sincerely
