answer: #Person2# shows #Person1# the way to the subway station because #Person1# will meet the separated friends at the subway station.
documents: #Person1#: Good afternoon, do you know where the subway station is?
  #Person2#: It's down the street about 2 blocks away.
  #Person1#: I've never been to this city before, so I'm not familiar with the city. Can I find it easily?
  #Person2#: I think so. Just walk down the street for about 5 minutes and you'll see a sign for it right in front of a post office. Keep walking for about 10 minutes and you'll be at the subway station. So, are you here to visit friends or for business?
  #Person1#: Actually, I'm with 2 friends to go sightseeing. We got separated while we were shopping in the mall, so they went to the train station and are now waiting for me there.
  #Person2#: Well, I hope you have a good time here in this city.
  #Person1#: Thanks.
