I have to roam the forums for my job...
My mom, while I knew she'd be OK with me, has kind of done more than what I would've expected her to do. Besides the fact that I started the meds without them knowing (so they didn't have a choice) she's been learning herself about the issue, instead of taking it at face value and just reading news articles (which I think a lot of parents do), goes to a support group of other parents who's children are T, has bought me a plane ticket to come back and go to a conference for trans folk, has asked me about my name, and when to start calling me she/her, etc. It's kind of overwhelmingly involved sometimes. I'm like, chill. It's not a fast process. Still looking/sounding like a guy, you shouldn't call me female pronouns.
My dad, on the other hand...is kind of, whatever. I'm your dad, you're my kid.

I hope all goes well with you.
