A substitute teacher who knows me was filling in for one of the gym teachers yesterday and loudly called me over by my birthname while my friends were gathered around him, then told the others to skidaddle, saying he "wanted to talk to her alone". Imaginably I had a heart attack, but they had left before he used a female pronoun and no one seems to notice that my birthname is obviously female. Maybe it's not Annie or Sarah or something like that but it's still a girl name. He only wanted to compliment my haircut, I explained quietly to him and he said it's fine and apologized if he had upset me or anything. He's a nice guy, just a bit annoying to have as a substitute because he does things very old-school and teacher-centered, we have a friendly rivalry any time he fills in for one of my classes.
They just think it's one of those dumb names parents give out of novelty to make a statement, I first thought that they knew I was trans but they don't appear to, I've been asked some very...male-specific questions before by people who did know my birthname (not the first time that guy has subbed in that class). I'll leave it at that

Also the lady upstairs from me who has known me since I was very little told me that I'm "a real gentleman" because I held the door for her, she recognized my mom and knows I don't have brothers or sisters. Yay for passing under unlikely parameters, when I went out yesterday I looked horribly feminine to myself too.
