documents: #Person1#: Hello, do you remember me? I bought some vases from you yesterday.
  #Person2#: eyes, you sent them to New York, right?
  #Person1#: That's right. I thought I'd come back to buy a few more souvenirs.
  #Person2#: What did you have in mind?
  #Person1#: Well, first, I'd like to buy a few postcards. My sister used to always send a postcard to herself whenever she went anywhere. I want to do that, too.
  #Person2#: We have plenty of postcards to choose from here. The same designs can be found on these posters.

  #Person2#: Yes, we do. They're on the wall behind you.
  #Person1#: How much do they cost?
