If you won't make your gender clear by your actions and speech, then don't blame me if I mistake you for the opposite gender.

:)

Yeah, I've been mistaken as a girl for a lot of my life, especially before highschool when I could grow facial hair and have it not look like a shitty goat mustache. It's my decision to have long hair, and I didn't fault anyone who made that mistake.

I hope people can tell by how you act that you're not a girl.

Oh, of course! That's usually only if I haven't talked to someone before. Now that I'm older and I have facial hair and more distinct masculine features, no one really makes that mistake anymore.
