     Calvin Coolidge (1872-1933) was the thirtieth president of the United States. He looked down on a

person as being unworthy of respect who was too fond of talking about the details of others people's

actions and private lives because he had no time for small talks. The following two incidents clearly

show how Collidge treasured silence.

     When he was vice president, Coolidge had plenty of opportunities to participate (参加) in Washington's

social life, especially the many dinner parties. As be ignored the art of conversation, he couldn't exactly

make himself dear to his hostesses. One lady felt she could solve this problem. She placed him next to Alice

Roosevelt Longworth, daughter of the former President Roosevelt. Mrs. Longworth, a very brilliant

conversationalist (谈话者), began to talk in her usual charming manner, but all attempts to a wake the interest

on the part of the vice president were unproductive. Finally, being shamed into anger, she said, "I'm sure

that going to as many dinners as you do, you must get terribly bored."

     Without lifting his eyes from his plate, Coolidge said not very clearly, "Well, a man has to eat somewhere."

      Later, when he was president and once again at a dinner party, Collidge was seated next to an outstanding

society woman, one of those busybodies, who seemed to take delight in trying to change the lives of everyone

they met. "Oh, Mr. President," she spoke with too much enthusiasm, "you are always so quiet. I made a bet

(打赌) today that I could get more than two words out of you."
