How about, I beg your pardon, Mind Your Own Business (MYOB).
After 1.5 years of their virtue signalling, the deserve rudeness.
Or, a punch in the mouth...but I try not to be violent.
Thank you. That will be reserved for the very nicest of inquiries from strangers and mere acquaintances. Friends and family already know my position and wouldn’t ask such a question.
I still find it extremely offensive that anyone thinks they have the right to any information about my health or private life. The best way to make that point might be to ask an extremely intrusive question about them. My reasoning is that if they’re that oblivious to the inappropriateness of their question, then they’re going to need a sledgehammer-style reply to clue them in. I’m operating on the premise that most reasonable people already know the question is wrong.
