I talked to my father today about "the whole trans thing". He's known for over a year now, but when I had to get off the phone to clock in for work, he ended the conversation with, "Love you, son. Talk to you later".
Had I not been standing right outside work, I would have gone straight to screaming.
Coming from a complete stranger, it's no big deal. I work at a hotel, so I deal with hundreds of people every day that I will probably never see again for the rest of my life. They're insignificant.
But when someone close to me, someone who knows me, does it...particularly if they make me feel like it was deliberate, it's infuriating. When my dad did it, I wanted to reach through the phone and smack him. I've posted pictures of myself all over facebook, changed my name, gone full-on girl, and he just keeps on. It doesn't always sound deliberate, but 9/10 times I can tell - he's doing it on purpose. I think it's denial, honestly. He wound up with two trans children, and can't accept that instead of big brother/little sister, we wound up being big sister/little brother in the end. And I understand. It's a big deal. But to put enough emphasis on the wrong pronoun that I can tell you're doing it deliberately? That's just plain annoying.
My SO does it all the time, but she's got the rest of her life to adjust, and she's just too stinkin' pretty for me to get mad at.
