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 only 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 you as a partner.
  #Person2#: Thank you for your compliments. It's just you are a good leader. Do you like the foxtrot and tango?
  #Person1#: Yes. And what dances do you like best?
  #Person2#: Disco is my favorite. I like it better than any other dances because it can release one's hidden feelings, and is a healthy exercise. But I don't do the rock and roll nor break-dancing.
  #Person1#: Oh, well, the music has stopped. Thank you for the dance.
  #Person2#: My pleasure.
