hayley (is it?), why dont you be up-front about it in that case? sometimes someone in class misgenders me, and i just casually let them know/correct them, and it has worked out pretty well. sometimes they'll ask a question or i'll realize they were misinformed/confused about my status so i explain it to them. people who are distant enough like colleagues or classmates usually seem pretty reasonable (as you can see through kelly's example?)
congrats kelly! it feels great doesnt it?
