My best friend went to the U.S.A. to study, and we haven't seen each other for almost a year. It's unrealistic for us to have face-to-face conversation. But thanks to emails, telephones and letters, we keep in touch until now. I really enjoy our communication. And from my point of view, letters, telephones and emails are good ways to communication.   Just what I says in the last paragraph, you see, the greatest benefit of the non-face-to-face communication is that I can contact with my friend at any time no matter what time is in the U.S.A..They are just unlike the face-to-face communication which is always restricted in the specific time and specific place.   What's more, they are best ways to escape from some embarrassing situation. I still remember once I did something wrong to my best friend. When I realized that I was wrong and wanted to say sorry for her, we hadn't talk to each other for a whole week. I don't know what should I do. Under my mother's advice, I wrought a sorry letter for her, I told her how regretful I was for hurting her and I really appreciated our friendship. After then she returned me a card on which she wrought that let us forget the sad things. And I knew I was forgiven. The letter saved our friendship.   Finally, some ways of non-face-to-face communication is a courtesy.For instance, when a couple invite others to their wedding, they send inviting cards to the guests. It's a way make others feel they are important to the couple and give the guests a chance to choose whether they attend the wedding or not.    I have to admit that face-to-face communication has some advantages such as communicating in time, but for me, I think other types of communication is much better because they're not restricted by time and places and they are the best way to avoid embarrassment. As a courtesy, they also play very important roles in our social life. So it's unfair to say that face-to-face communication is better than other types of communication, such as letters, email, or telephone calls.
