I'm sorry if this is not the right board but I didn't want to post in AIBU as there can be a lot of volatile people on there.
Basically I teach a night class for adults and I'm pretty sure I just got someone's pronoun wrong infront of the whole class and I am absolutely cringing and so embarrassed. What should I do? Pull them aside next time and quietly apologise? Ignore it and use "them" next time or something else? I feel so archaic in that it just slipped off the tongue and I don't want to make anyone feel uncomfortable or unwelcome. I am absolutely kicking myself!
