Today is the 21stcentury, as the highly developed of technology, we facilitate our life with all kinds of newly invented products, such as computer, digital camera and so on. The technology products indeed brings us convenience, the old way of doing things has been challenging. Before, people like to write letters to say hi to others or send letters to give people information, while today, people can use smart phone or computer to call others quickly, that saves a lot of time. Does the way of writing letters will be kicked out and disappear? Well, on my opinion, though people like to use the new technology, letter still has its charm. Writing letters means someone is in sincere attitude, the one who receives the letter will be touched deeply. Sometimes message is hard to use phone to explain, then letters will be used. In a word, writing letter will be not out of day.
