I remember I had told my one super-close friend not too long ago and I was like, "So, I'm sure you were like surprised at first--"
and he's like, "No. Not really. You always just seemed different. I don't mean that in a bad way. You're just yourself. You're becoming more like yourself." and he also said that mainly I don't really act any different then before, except I seem happier and more confident. He still makes some pronoun and dead name slips now and then, but he's certainly trying, and that reaction meant a lot to me.
My other best friend was also really supportive. He was there really early on when I thought maybe I was just a crossdresser, but the trans-ness of it all quickly became apparent, and since the time I eventually told him plainly that I was a trans woman and what name to call me, he hasn't deadnamed or misgendered me once and we've known each other since pre-K. He only says my old name referencing me to people I haven't come out to. lol its kind of crazy to think he did that so naturally when a lot of people I've only known since high school have a lot of trouble with it still. I think it kind of helped him being a fan of Against Me! because he was like sort of aware of trans stuff via Laura Jane.
my grandmother (who is totally my bestie and my mom more or less) is mainly pretty supportive after a lot, a lot, a lot of explaining, (even got p.o.'d about the bathroom bills with me) but she annoys me a little bit when she sometimes says, "they didn't have all this back in my time. things are so different now."
and like yeah, there was a lot less treatment, but trans people are just more visible, there aren't more of them. then again she also told me rock, paper, scissors was "after my time, hon" and that she didn't know how to play lol
