documents: #Person1#: Could I speak to Mary, please?
  #Person2#: This is Mary speaking. Who is that?
  #Person1#: This is Bob. Where have you been, Mary? I have been trying to get on to you for the last half hour. Don't you leave your home at 7
  #Person2#: Yes, I do, but today I went shopping and have only just come back. It is very nice to hear your voice, Bob. I didn't know you were in New York.
  #Person1#: I arrived this morning. I would have rung you before but I have been terribly busy all day attending a conference. It has only just ended. Are you doing anything tonight, Mary?
  #Person2#: Yes, I am going to meet a client.
  #Person1#: But that is terrible! I am only here for one night!
  #Person2#: I am sorry, Bob. If you had told me you were coming up, I would have kept tonight free. But you didn't tell me.
  #Person1#: I didn't know myself till this morning when my boss suddenly dashed into the office and told me to rush up here to attend the conference.
  #Person2#: I thought Henry usually did the conferences.
  #Person1#: Yes, he does but when he was driving up here last night he had an accident and was taken to hospital. So I am doing it instead. Mary, Must you go out tonight? Couldn't you get out of it?
  #Person2#: I'm free tomorrow but I suppose that will be too late.
  #Person1#: No, I will stay another day. my boss will get over it. Would you like to meet me for lunch tomorrow?
  #Person2#: I'd like to. But Bob, are you sure it will be all right? I would hate you to make your boss angry or even lose your job.
  #Person1#: It is all right. I will call the boss and tell him I am staying another day. I stayed an extra night in Boston last month and he didn't seem to put about it.
  #Person2#: Why did you stay an extra night in Boston? What happened?
  #Person1#: I will tell you tomorrow. See you tomorrow, Mary.
  #Person2#: See you tomorrow.
