There's someone who's been in the pub I work in a few times over the last year or so, and I've always thought that maybe she's trans, and there's been an urge to talk to her/find out if she really is, and then I've realised there's no point to it. It would be the only thing we have in common, she's old enough to be my grandmother, and she seems completely different to the majority of the people I get on with around here, the builders and painters. If I asked around someone would know, but I don't need to know, and I'm sure she doesn't need someone drawing attention to her when she could easily be living as stealth.
If any of you lived in my area, which you don't, I might suggest meeting up and talking in real life, but approaching a complete stranger on the basis that they might also be trans? No. I'm not going to make people uncomfortable and potentially end up outing them for no reason when I can get my fix of being able to vent and talk about trans issues on here.
And if someone approached me my natural reaction would probably be "Hell no!" or something more explicit. Not because it's bad to be trans, but because that's what I'm like. When I identified as a lesbian one of the chefs asked if I was gay because he read my coming out (as liking women) thing I'd posted a year or so before on facebook and I denied it like hell for no reason.
