KG, truth is, I have no idea how I would "react" in the moment. That's why most comm with my W is still by email only.

eg. Only two days ago, my W asked me a question about D10's b-day money from my parents. It is good that the question was by email, because my initial reaction was, "how dare she ask". The reality was, the trigger was not WHAT she asked... it was how it "sounded" to me.

I still have yet to have that moment of STFU when my W asks me a question in person, that sets off my triggers.

The trigger is the same as what it sounds yours is. And that, like me, you may have trouble "thinking on your feet", so coming up with that good response... well...

Honestly... I don't have any real good feedback for you. Adinva gave great advice. If that moment ever happens again... try to say nothing... or even say something obviously off centre to throw humour into it... or simply say, "Sorry, I do not understand the question."
