Okay, so, I'm agender and I've had people call me a he, an it, and basically every pronoun their little brains can think of. I use any pronouns and all titles, so they're always right with whatever they address me as, and I think it's hilarious when they're like "Sir..." or something, trying to upset me, and I just answer their question or statement normally.
I'm invincible when it comes to misgendering ;3
