answer: Linda lost her way to visit Nelson so she calls to tell him she is in a bookstore. Nelson knows where Linda is and directs Linda to reach a six-storied apartment house.
documents: #Person1#: Hello. Is that Mr. Nelson? This is Linda speaking.
  #Person2#: Hello, Miss Linda. What can I do for you?
  #Person1#: I'm on my way to visit you now, but I've lost my way.
  #Person2#: That's too bad. Where are you now, Miss Linda?
  #Person1#: I don't know exactly. I think I'm somewhere on New Hampshire Street. I'm calling you from a bookstore.
  #Person2#: A bookstore on New Hampshire Street. It's at a corner, isn't it?
  #Person1#: Yes, it is. And I can see a restaurant at the other corner.
  #Person2#: Now I'm almost sure where you are. You turned at the second corner. You should have turned at the first corner from the railway station.
  #Person1#: Is that so? Then I'll go back to the first corner.
  #Person2#: It'll be better that way. You'll find a one-way traffic sign. That's where you have to turn to the left. Come up the slope to reach a six-storied apartment house. My room is on the third floor.
  #Person1#: I'm sure I won't have any trouble this time. Thanks.
  #Person2#: I'll be waiting for you. Bye.
