I don’t want to enflame the sensibilities of some posters, but for me now “they”in the singular usually connotes a trans individual. Last week I did a research trip that included 10 hours of driving with a coworker/good friend whose daughter (who I know well) goes by “they” and it’s became normative for me now.
Lots of trans people just use "he" or "she".
On this forum it’s simpler just to use a short version of the forum name than guessing at a personal pronoun
You're right, Sci.
