answer: #Person2# arrives in Berlin and it takes 19 hours by bus. #Person2# takes the bus because it is more environmentally friendly. #Person1# suggests #Person2# come by plane next time.
documents: #Person1#: Hey. Welcome to Berlin. It's great to see you again.
  #Person2#: Yeah, good to see you, too. Have you been waiting here at the station long?
  #Person1#: Only 15 minutes. But let's get out of this cold and go to my apartment. How are you feeling after that long bus ride?
  #Person2#: Ah, it wasn't too bad. It was only 19 hours.
  #Person1#: That's crazy. You could have flown here from London, for 60 euros and it would only have taken an hour and a half. Was it really worth all that time just to save a bit of money?
  #Person2#: Well, it was a pretty uncomfortable ride. To be honest, the bus was starting to smell toward the end of it. And there was a man next to me, who was breathing really loudly while he was sleeping. But the reason I took the bus was because it's more environmentally friendly than flying.
  #Person1#: I think it's great we want to help the environment. But you look so tired right now. I just think you should be a little more careful with your health.
  #Person2#: Well, I wasn't expecting the bus to be so unpleasant. But you're right. Next time I visit you. I'll probably fly.
