【单选题】
听力原文:'Is there any mail for me?' you often ask when you return home at lunch or dinner time. If there is a letter, you read it eagerly, pleased that your friend or relative has thought of you. Other people respond as warmly as you do to a friendly letter. They are happy to be remembered. But if the letter you write makes them feel as if you yourself were with them, speaking in your own friendly way, they are especially pleased. You have given something of yourself. And to be yourself in a letter to a friend is an art you need to master. Why are you pleased when you hear from your friend or relative?
A.
Because you needn't write him a letter.
B.
Because you can collect stamps.
C.
Because you are remembered.
