documents: #Person1#: Hi, sir. Come and have a look here. We have all kinds of sweaters.
  #Person2#: I'm looking for a sweater for my wife. Tomorrow is her birthday. And I know she needs a woolen sweater.
  #Person1#: How do you like this grey one? It's pure wool, one hundred percent of Xinjiang wool.
  #Person2#: It feels good. Are there cowl-neck pullovers with the same color? My wife prefers a turtleneck to a V-shaped collar.
  #Person1#: Yes, we do. What size do you want?
  #Person2#: Size one. By the way, what if I bring home this sweater and my wife doesn't like it?
  #Person1#: Well, you can always bring it back to us for a full refund.
  #Person2#: All right. Could I have it gift-wrapped, please?
  #Person1#: Yes, just a moment, please.
