The other day when my daughter and my son-in-law drove us somewhere, we were talking about my son and his girlfriend, who would later arrive at San Francisco to join us.

The couple have been together for three years.  My wife and I like that girl, at least we don't have any bad impression of her.  So we should have a daughter-in-law ourselves, shouldn't we?  The problem is my son hasn't popped the question yet. 

My daughter asked me why didn't I push her brother a little bit to make up his mind quick.  I replied to the question that I dare not to do so because that is his personal affair, and all I can do was once when I wrote him I reminded him of the subject idiom.  You know what?  My daughter and my son-in-law burst into laughters and said with one accord, "Dad, you are really old-fashioned."
