I have a very good friend, and we knew each other when I was in my hometown. Now as I move to another city, we don’t see each other often, but we keep in touch with each other by writing letters. Though computer provides people a very convenient way to communicate, we like the original way, because we want to share every happy moment. When writing down these things, we can recall of the happy moment again. What’s more, writing a letter is much sincere, which is the important reason why we can keep our friendship. I cherish our friendship so much and hope it can last forever.
