If you ask her what is a favorite story she has written, she will hesitate for a long time and then say it may be this story that she read in a book once: an English language teacher in China asked his Chinese student to say what was the happiest moment in his life. The student hesitated for a long time. At last he smiled with embarrassment and said that his wife had once gone to Beijing and eaten duck there, and she often told him about it, and he would have to say the happiest moment of his life was her trip, and the eating of the duck.
