Mostly just my own mind. Most people in the department know I am trans since I joined pre-transition, but now, I am stealth to the new people who have come in. But there is a good chance, with so many people knowing and me having to be so open about it before, that they could out me to the new people. One of the new people really does not like transgender people...and has made no bones about it. Definitely thinks I am cis too. And she likes me. She laughs with me and we have nice conversations. I've been trying to say to myself "if they out me, even by accident, it's no big deal..." But truthfully, I think I'd be heartbroken because this is the first time I've felt normal in a very long time. Someone actually talks to ME, as a person, instead of just asking about my transition and being fascinated by it all.
