Japanese style conversations develop quite differently from Western-style conversation.
    A Western-style conversation between two people is like a game of tennis. If I introduce a topic, a conversation ball, I except hit it back. If you agree with me, I don’t expect you simply to agree and do nothing more. I expect you to add something—a reason for agreeing, or another example to carry the idea further. But I don’ t expect you always to agree. I am just as happy if you question me, or completely disagree with me. Whether you agree or disagree, your responses will return the ball to me.
    A Japanese-style conversation, however, is not all like tennis. It’s like bowling. You wait for your turn. And you always know your place in line. It depends on such things as whether you are older or younger, a close friend or a stranger to the previous speaker, in a senior or junior position, and so on. When your turn comes, you step up to the starting line with your bowling ball and carefully bowl it. Everyone else stands back and watches politely, giving encouragement. Everyone waits until the ball has reached the end of alley, and watches to see if it knocks down all the pins, or only some of them. Then, after everyone is sure that you have completely finished your turn, the next person in line steps up to the same starting line, with a different ball. Your ball is not returned.
