Of course some explanation to the missus, like "that's not for you dear, that's to remind my own self, daily. You go ahead and talk to me whenever you so desire", would be necessary? Hmmm, and some form of tape which won't degrade, dry out and be difficult to remove, perhaps?
Just being helpful here, and constructively intelligent (in three paragraphs or less).
I hope you have the integrity to tell CB exactly who gave me the idea of using that to settle matters.
