answer: #Person1# can't attend a meeting in Washington and asks #Person2# to go and introduce their products instead. #Person1# then gives #Person2# some tips of the trip and the reimbursement.
documents: #Person1#: I can't attend the meeting in Washington. I'Ve proposed you as the most able substitute.
  #Person2#: But I'Ve never been on a business trip before!
  #Person1#: It's easy enough. Just make sure you keep track of all your expenses. The accounting department will reimburse you for all your meals and travel expenses.
  #Person2#: So the company will pay for everything?
  #Person1#: Yes, but when you send in your expense report, you also have to file a report summarizing your trip. It's not just a big vacation, you know.
  #Person2#: That sounds good. But what do you want me to do there?
  #Person1#: I'Ve already paved the way. You just have to give a presentation on what our products are. I will do the follow-up and close the sale.
