documents: #Person1#: I need a haircut.
  #Person2#: Do you have an appointment?
  #Person1#: No, I don't. You look pretty busy today. Do you have an opening for me?
  #Person2#: Yes, we do. I can cut your hair right now if you like. Do you need a shampoo too, or just a haircut?
  #Person1#: Just a haircut. I washed my hair this morning.
  #Person2#: Alright. I will have an assistant wet your hair. Then I can cut it. Please step over there. How would you like your hair cut today?
  #Person1#: Well, I last had a haircut eight weeks ago. So my hair is pretty long. But I want the same style.
  #Person2#: I recommend you leave it a little long on top. But we should take in the back and sides a bit more. That's more fashionable now.
  #Person1#: Alright. You are the expert. I'm happy to have your recommendation.
  #Person2#: So I will cut the sides just above the ear. Is that good?
  #Person1#: Fine.
  #Person2#: And do you usually part your hair along here?
  #Person1#: Yes.
  #Person2#: Alright, I know just what to do. Your hair seems quite dry, you know. And I see some split ends.
  #Person1#: Yes, I know my hair is quite thin. It runs in my family. Everybody has very thin hair.
  #Person2#: The problem is the split ends. They make your hair look even more frizzy.
  #Person1#: I don't know what to do about it.
  #Person2#: Well, there is just one thing that you can do. That is, don't blow-dry your hair for so long after you shower. Let it dry naturally. That is easier on the hair, so you won't get split ends.
  #Person1#: Do you sell conditioner here?
  #Person2#: Of course. I have one I can suggest.
  #Person1#: Great. I would be happy to try it. I know my hair doesn't look good now. It's too weak.
  #Person2#: The problem is the split ends.
