documents: #Person1#: Hi, Sara, what are you reading?
  #Person2#: Hi, John, I am trying to find a carpenter.
  #Person1#: Why?
  #Person2#: Well, I want to build a deck in my back yard.
  #Person1#: What for?
  #Person2#: So I can have a special place to hang out with friends, and also do some barbecuing on weekends.
  #Person1#: That sounds cool. Do you mind if I recommend myself for the job?
  #Person2#: You? Do you have a carpenter's license?
  #Person1#: Yes, of course. But I only freelance on weekends with my uncle.
  #Person2#: Wow! That's cool. So, let me give you some details about the deck I want.
  #Person1#: Please go ahead, I am listening.
  #Person2#: I'd like my deck to be at the same level as the back door.
  #Person1#: Is your back door higher than the ground level?
  #Person2#: Yes, the back door is about four or five steps higher than the ground.
  #Person1#: Okay, then you need a deck with a guardrail.
  #Person2#: I don't like things to be fancy.
  #Person1#: Don't worry. I will build your deck with a simple but classic look.
  #Person2#: Hmm, that's good. Can you use cedar or redwood to build it?
  #Person1#: Cedar is a good choice.
  #Person2#: Well, let's take the measurements right now.
