I’m usually pretty open- minded and often find myself saying “hmmm, that’s a good point” when I’ve had a hot take on an AIBU question that’s been challenged by a response that made me rethink. But I have actually read this whole thread and I haven’t come across one single response that makes me rethink my hot take YABU. I’m American, though have lived in the U.K. almost 25 years, during which time I’ve gotten (yes, that word that makes so many teeth itch!) married and had two kids here in the interim. I’m always addressed as Mrs DH’s-surname when I’m doing stuff for home, kids’ schools etc. People assume I’m Mrs regardless of whether I’ve told them. But I also use my maiden name at work, and sometimes I even get addressed as Mrs maiden-name. COULD NOT CARE LESS.
It’s always a little strange at first when I go back home to the US, because there the default for any woman, married, single, divorced, widowed, whatever is Ms - for example, newspapers like the NY Times almost always title a woman Ms unless she’s the First Lady. But again, I just shrug, COULD NOT CARE LESS. It would never occur to me to tell someone to address me as Mrs, even though I have achieved that higher state of being called marriage. As my Southern daddy used to say, “you can call me anything you like, just don’t call me late for supper!”
The OP is entitled to her opinion on her title and to politely request that the pharmacy change their records to the title/honorific she prefers (which, let’s be absolutely clear, IS NOT HER NAME and is not a key piece of information the pharmacy needs to match to be sure the prescription is properly dispensed to her), but I’m sorry, i do think SIBU to equate a minor admin error with an affront to her dignity.
