From my mom, who's pretty accepting but doesn't quite get it sometimes. "Okay, so if you're a guy, why are you painting your nails/letting your hair grow/wearing skinny jeans/other gender stereotype?"
"So it's like you're living a lie?"
And I know MTFs get more media exposure, but it's kind of weird to me how a lot of people don't realize that FTMs exist at all. Even if they're accepting.
"You're already so feminine, you'll make a great girl!" - But I guess that just means I'm passing so I can't get too upset about it.
"Wait, so you were a guy and then you changed into a girl, and now you're changing back?"
"Wait... you can do that?"
