documents: #Person1#: How do you like this waltz?
  #Person2#: It's very nice, I like it very much.
  #Person1#: Well, then, may I invite you for the first dance?
  #Person2#: My pleasure. But I'm afraid I'm not much of a dancer, and I suppose you dance often.
  #Person1#: Me? Oh, no. In fact, I took up dancing quite recently.
  #Person2#: Oh, really? But you're doing the waltz wonderfully well.
  #Person1#: I'm glad you say so, you dance beautifully too. It's lucky that I got a partner.
  #Person2#: Thank you for your compliments. It's just that you are a good leader. Do you like the fox-trot and tango?
  #Person1#: Yes. And what dances do you do best?
  #Person2#: Disco is my favorite. I like it better than any other dances because it can release one's pent-up feelings, and is a healthy exercise. But I don't do the rock and roll and the break dance.
  #Person1#: Oh, well, the music has stopped. Thank you for the dance.
  #Person2#: My pleasure. Let's go and have a drink.
  #Person1#: Fine.
