Let A be the subject of the argument.
Husband knows A=true. A has been true all of his life. It is commonly known by all sentient beings that A=true. It is one of the bedrock strictures of his life.
In a conversation with Wife, Wife mentions that A=false. Husband questions this. No, she says. A is false, has always been false, and only a complete idiot (like Husband) would think otherwise.
OK, thinks Husband. She is the light of my life and I must support her. Let A be false forever.
Soon afterwards, Husband comes across a situation where he must act on A. His first instinct, nurtured by years of life experiences, is to assume A=true. But wait, he thinks. Wife said A is false. I don't want to get in trouble with Wife, so I will act as if A is false. He proceeds to do so, and feels good about it.
A while later, Wife comes along and observes that Husband has acted as if A=false. Husband proudly beams as he awaits his well-deserved praise.
Wife flies off the handle. How could you possibly think A is false?, she hisses in her best third-grade teacher sneer. Any idiot knows A is true.
But you said A is false, Husband replies.
I never, ever said that, says Wife.
Yes, you did, answers Husband, as the room begins to spin. You stood right there and told me A is false.
Not only did I never, ever say A is false, Wife opines, but I've never stood right there, either.
Husband rubs his temples and heads off, mentally, to a happy place (like his old bachelor apartment) and hunkers down for the obligatory 45-minute oratory on his failures as a husband, a human being and a carbon-based life form.
