One of my friends is nonbinary but they looks super masculine. Deep voice, into powerlifting, etc. I introduced them and their girlfriend to my parents when they were in town. Later my mom was so confused. “How can someone be attracted to women if they’re non-binary”? She has been a high school teacher for forever. She’s had plenty of students that were trans or used different pronouns than she assumed. I was so surprised that this sort of thing would slip through the cracks.
