Conversation with my mother-in-law this morning
This conversation in the OP reminds me of an old joke.
A roofer is teaching his apprentice how to hammer down the shingles. He places the nail in the appropriate place, and says to the apprentice, "When I nods me head, hit it!" He nods his head, and splat! the apprentice whacks him a good one.
It's like talking to a moron - 'does not compute'.
