answer: Max is calling Mr. Nelson's office to speak to him about the Girard case, but #Person2# tells Max that Nelson is away. Max has missed Nelson a few times so this time he leaves his name and phone number so Nelson can call him back.
documents: #Person1#: Hello! You have reached the offices of Maddox and McKnight, can I help you?
  #Person2#: Yes, my name is Max Richards. May I please speak to George Nelson? I have already called several times. It seems I always catch him out of the office.
  #Person1#: Oh, I'm sorry. Mr. Nelson is away at the moment. I'm sorry that you keep missing him while he is out of the office. Would you like to leave a message?
  #Person2#: I'm sorry, I didn't hear you clearly. Could you repeat that please?
  #Person1#: Certainly. Mr. Nelson can not take your call at the moment because he is away. He stepped out of the office for the whole afternoon and is not expected back until tomorrow morning. His schedule is very unpredictable at times, so the best way to reach him is to first make an appointment by email or text messaging.
  #Person2#: Can I leave a message for him please?
  #Person1#: Of course, can you leave your name and number? I'm sure Mr. Nelson will return your call as soon as he is able.
  #Person2#: My name is Max Richards, my phone number is 898-3423. Could you ask him to call me back as soon as he gets back, please? I have a rather timely matter to discuss with him.
  #Person1#: Can you tell me what it's about? I can make a note of it, so Mr. Nelson is aware and prepared when he returns your call.
  #Person2#: Yes, please let him know I would like to discuss the Girard case with him.
