  #Person2#: not really. But it has puzzled me for a long time.
  #Person1#: what's the puzzle?
  #Person2#: my husband and I prefer to have no kids, but my mother-in-law is very traditional and wants grandkids.
  #Person1#: oh, I see. I think the older generation tend to think in a different way.

  #Person1#: oh, really? Maybe she is just eager to see her grandchildren.
  #Person2#: but it's absolutely our own business to have a child or not.
  #Person1#: definitely.
