answer: Although the business conversation was successful, Francis thinks the trip was a nightmare because he was unlucky to lose his luggage on the return flight.
documents: #Person1#: Hi, Francis, how was your business trip?
  #Person2#: It was a nightmare.
  #Person1#: What ' s up?
  #Person2#: Actually, the business trip itself was very successful. We arrived on time, we had nice conversations and we settled some important issues for the next year.
  #Person1#: Sounds quite fruitful, why do you call it still a nightmare then?
  #Person2#: Well, the air line lost my luggage on the return flight and then I lost my carry on bag when I was tackling with the officers in charge. I left the airport three hours later than I expected and then I was caught in a traffic jam. When I finally got home, I was totally exhausted. But I found the elevator was out of service due to a blackout.
  #Person1#: This is really a sad story. Did they trace back your luggage?
  #Person2#: I am still waiting for their call.
  #Person1#: Take it easy, all sufferings have their reward.
