Thanks to development in technology,we are able to communicate much easier than before. Telephone,fax,and Internet bring so much convenience to our daily life. However, if possible,I still prefer writing a letter to a friend or relative in ink instead of striking the keys on a keyboard. Writing and reading a letter is not only for the sake of telling about something,but a way to make the reader share the feelings of the writer. After a day's snowing, the ground,trees and buildings were all covered with white snow,and the air was so fresh that you couldn't help taking more deep breath. Then you thought of one of your good friends in the far south,and you were eager to let him share the beauty of such a snowy night. You just took out a piece of dark blue paper on which you could write down your fondness and sentiment with white fluorescent pen. Then you sealed it well, and put it into a mailbox. A letter with your feelings would arrive at your friend within a few days.
