Does saying anything at all before the silence mean that it doesn't fit this category?
Recently, at a reception immediately after a memorial service, Jake, the husband of one of my wife's distant relatives greeted me. As we were shaking hands he smiled, looked me in the eye, and said, "Haven't seen you at a _____ family reunion in years."
I replied by looking him back in the eye, grinning, and saying "That's right" followed by an unusually long silence on my part.
It is unusual for me to use silence. Ordinarily I'd have continued the conversation about that topic, or at least asked a follow-up question to encourage the other person to talk.
At that very moment, though, I was almost literally reeling from an extremely unpleasant encounter with two of my wife's particularly boorish relatives who had ambushed me as I had walked into the reception room at the funeral home, immediately before I saw Jake.
I wasn't sure if Jake was getting ready to criticize me for missing the reunions, or if he was going to tell me he wishes he could miss the reunions, too. At that point, immediately after my extremely upsetting encounter with the boors, I didn't want to discuss my wife's family with anyone.
So I just said, "That's right" with a grin and said nothing more.
Jake looked at me for several moments, silent himself, and then he changed the subject and started telling me about a trip he and his wife have planned.
The technique worked; Jake changed the subject to something I was comfortable discussing. Does the way I used it fit under this category?
