You just flipped that whole thing on its head pretty well… And also reminded me of one of two most cringiest times in my life where I misgendered someone. She worked at my local grocery shop and I had known her throughout her transition, but as an immigrant in Texas I was really keen on my “yes Ma’am” and " yes Sir" and I pulled out a “thank you sir” when visiting after a long time and she called me out on it as she should have… I felt like a dick, yet somehow did it again with a student of mine years later. I wish I had my wife’s excuse (she comes from a language that doesn’t have gendered pronouns and goes about her day confusedly dispensing he or shes in a totally random pattern 😂)
