I misgendered a woman who was already very irate. This was probably 30 years ago, before trangenderism was as common as it is now (or at least as publicly presented). It did NOT go over well, to say the least. Other customers were smirking and giggling, and even a coworker was having trouble keeping a straight face. In my defense, she was heavyset, had shaved hair and a raspy voice. Luckily I didn’t say any of this to her. I just got my manager and let her yell at me (and him) for 10 minutes. I learned the value of keeping your mouth shut until you’re certain that day.
I do Semantle. It’s sort of like a hot or cold kind of game where there is a word of the day and you guess words and they are scored as to how close they are semantically. You have an unlimited number of guesses and also a seemingly unlimited number of hints. Even with the hints it sometimes takes me 60 guesses, but sometimes it’s 5 or 6. There is a link to the paper where they discuss the relativity model they use. I find it challenging.
