台湾籍旅美老师今天交给我们的句子是:
Another way that you can use which we often use to be polite to the other person is rather than indicating that you are in a hurry to go, you turn around, and you say to them, "Well, I won't keep you any longer. You're probably busy." Or, "I'll let you go."
另一个常用的礼貌道别方式就是,暗示对方你有急事必须离开。你转身,并说:好我就不耽搁你了,你大概很忙
