Of course I know. I wish I couldn’t tell. I’ve been saying the serenity prayer under my breath for the last hour or so.
"I know that you know that I've been drinking!"
"That's right, and now I know that you know that I know that you know that you've been drinking".
It could go on forever...
My experience is that alcoholics a) don't like it when you change "the rules" (spouse gets upset when I drink - so why is she now not getting upset?); b) think they know what is happening inside your mind because they don't have proper boundaries ("I KNOW what you're thinking, so why aren't you acknowledging it??").
It sounds like you are doing a great job at maintaining your calm.
