answer: #Person2# tells #Person1# where the nearest post office is twice and suggests #Person1# buy a guidebook.
documents: #Person1#: Excuse me, I am a stranger here and I'm looking for the nearest post office.
  #Person2#: That's no problem, turn right at the next corner, continue four blocks and there's one next to the police station.
  #Person1#: Could you repeat that one more time?
  #Person2#: Sure, take a right at the corner and after 4 blocks. You will see a police station. It's next door. Why not buy a guidebook to the city? You can get one at any drugstore.
  #Person1#: That's a good idea, thanks a lot.
