I know a lot of trans people second-hand, but not first-hand. So I have not had the opportunity to ask anyone directly. A cousin of mine from Canada (the other side of the world to me) is transfem. A step-cousin-in-law is transfem, but I haven't met her yet because the step-father-in-law is anti-trans (which I have been vocal about disagreeing with him on).
Anyway, thanks. I'll take your advice on referring to them by their post-transition name and gender, even while referring to them pre-transition. Peace!
