When we want to communicate with our relatives or friends, what will we do, to make a call or write a letter? Now let’s compare the advantages of a call and of a letter. Generally speaking, most of us would prefer to make a call nowadays. Firstly, it is fast so making a call can save us time. None of us wants to waste time in this competitive society. Then the telephone functions well in this aspect. In addition, making a call brings us convenience because we can do so wherever and whenever we like. Also, we can communicate with people in the casual way of chatting on the phone, which seems to be friendlier. With the development of hi-tech, man has realized the dream of talking face to face on the visual phone, thus bringing people together and reducing the homesickness of many people far away. However, writing a letter for greetings has its own special advantages. As we all know, it is much cheaper than making a call. Not only can writing a letter save us money but also it shows more respect and sincerity to others. For instance, when you want to invite someone to your party or to dinner with you, you’d better send him an invitation letter, which is more formal than just making a call. Times are constantly changing, and yet writing a letter is still as good a way as making a call. Of course which on earth should be the more proper way depends on the individual personal purpose.
