I've become more or less stealth. I go about my day passing without even a second glance. I feel if its no ones business then why tell em? Even the people who've known me since before transitioning, they've more or less forgotten the person from before. Obviously the memories are there but they recount them like the me now was the me then. (If that makes sense?) Even in the changerooms at work, there's been 'gossip' that there's a trans person in our changeroom, one lady asked me what I thought of it, I responded with 'I think we should be absolutely awful to her for no reason other than some of us think she isn't the same as us.' with HEAVY sarcasm. Everyone laughs, and tells the lady to stop being such a B and mind her own business.
My mother asked me once how I felt about the 'old' pictures around her house, and if I wanted she take them down, I said 'no, I'm not going to pretend that was never me.' This opinion may change in the future..
I believe in full disclosure with people in a relationship, I also see it as a good 'filtering' system for crappy people I wouldn't want to spend time with anyways. I don't ever 'lead' with 'HEY GUESS WHAT, I'VE GOT A DONG..!' though.
