documents: #Person1#: Can I also take the MET to get there?
  #Person2#: Yeah sure, it's much quicker. Do you know how?
  #Person1#: No, can I trouble you to lend me a hand?
  #Person2#: Ok, not a problem. Let's go to the station.
  #Person1#: You have to buy a ticket first. You want to go to Shi Da, right?
  #Person2#: Yeah.
  #Person1#: Ok, then you need to go to Tai Power Building Station.
  #Person2#: Where is that?
  #Person1#: Look at the map to see where you are. Then look at where you want to go. The number is how much money you have to pay.
  #Person2#: Oh, that's simple enough.
  #Person1#: Then, when you have your ticket, you go wait on the platform.
  #Person2#: Anything else I should know?
  #Person1#: Just remember to hold on to your ticket. You need it to get out of the station when you get there.
