documents: #Person1#: Sue, there you are. Have you got time for a little chat?
  #Person2#: Of course. What is it, Mike? Is something wrong?
  #Person1#: No, not really. But I'll like your advice.
  #Person2#: I'll help if I can.
  #Person1#: Well, you remember Miguel who stayed with us last summer?
  #Person2#: No. But I remember you telling me about him. He was very fond of sightseeing, wasn't he?
  #Person1#: That's right. Well, I got a letter from him this morning and he's invited me to spend a holiday with his family this year. They have got a big house on a river side, and they've got a boat. You know how crazy I am about boats.
  #Person2#: Mike, that's great. What a wonderful chance for you!
  #Person1#: Yes, but it's not that simple.
  #Person2#: What's the problem?
  #Person1#: It's Celia. You see, we've both been saving like mad to go on a trip together this year.
  #Person2#: Ah, I see. You don't want to disappoint her, of course.
  #Person1#: That's right. She'd be so upset. She's been doing all sorts of jobs in her free time. She is well worthy of this holiday. It seems so unfair.
  #Person2#: Look, Mike. First, you must tell Celia about the invitation. She'll understand your problem. But why don't you tell Miguel about the plan you had already made with Celia? He might even suggest a good way to settle the problem.
