Telephone and letter are two main means of communication; they both have their advantages and disadvantages. Communicating with other people by telephone is convenient, speedy and direct. For example, if one of your family members is seriously ill at night you can dial 120 to ask for help. Besides, friends can chat through the wire. It seems that telephone shortens the distance between people. Men can keep in touch easily. However, communicating by telephone seems much more expensive than by letter. And by writing letters people can not only greet each other but also exchange their ideas. But it is slow to communicate by letter, especially when you have something urgent. In my opinion, we’d better combine these two ways to make our communication better.
