A famous American writer was visiti

A famous American writer was visiting Japan last year. He went to a university to talk to a large group of students. As most of them could not understand English, he had to have an interpreter（翻译员）.
In his talk, he told an interesting story. He spoke for a long time and then stopped for the interpreter to put into Japanese. But he was very surprised that the interpreter did this in a very few words, and all the students began to laugh.
After the talk, the writer thanked the interpreter for his good work, and then said to him, "Now please tell me how you could put my long story into a very short Japanese one."
"I didn't tell the story at all," the man answered with a smile. "I only said, 'Our American friend has just told a very interesting story. Now please laugh, all of you!"
