I'm not that surprised by the people who regularly see me. Its the people who haven't seen me before. I've had a case of people who last saw me a few years before I started HRT not recognize me despite me hanging out with my siblings in our parents house (just like the last time I saw them), so I know its not just me who thinks I look quite a bit different.

But looking more like my sister than myself 4 years doesn't translate to people gendering me as anything but a guy even if they've never met me before. TBF, I'm an NB, I often have facial hair, I haven't really voice trained, and my presentation certainly isn't feminine.
