  #Person2#: 0K. Well, I suppose I have no choice. What do you want me to do?
  #Person1#: What time is the most convenient for you to change rooms, sir?
  #Person2#: I'm going out in about half an hour.
  #Person1#: What time will you be back?
  #Person2#: Oh, around seven o'clock, I suppose.

  #Person1#: Thank you very much, sir.
