Well, you and your wife have developed by now a gentle and effective language. Suffice for her to use "kitty" eyes and you get the message. I doubt such approach would be effective for that lady.
I believe in straight forward approach to deliver a message. Gentle ("even the most bitter medicine can be given with a smile"), yet "in your face".
But each couple has their own ways.
Thanks again for sharing episodes from your practical life. 👍
