answer: John and #Person2# talk about the difference between Chinese and American relatives after #Person2#'s uncle and aunt came without a call.
documents: #Person1#: Well, I can't believe your uncle and aunt came to stay with us for a week, and they did not even call us in advance. 
  #Person2#: John, they are old-fashioned people from the Chinese countryside. That's their custom. 
  #Person1#: I know, but it is hard for me to get used to your relatives coming to visit us, and without warning. 
  #Person2#: Don't your relatives visit other relatives? 
  #Person1#: Yes, but Americans never visit without calling in advance, and they almost never stay overnight. 
  #Person2#: I think that maybe Chinese families are closer than your families. 
  #Person1#: I think you're right!
