I didn’t vote, since the 2 questions posed are not “yes/no” questions.
That said, the age mix of the environment I find myself in doesn’t matter to me terribly, although I suppose I do not consciously wade into groups of kids (i.e., under 21). I also avoid boozy and/or smoking locales, not because of age concerns, but simply because I hate tobacco smoke and don’t find much endearing ambience in bars or nightclubs. But, hey, I live 24/7 as a woman, legally am a woman (got the paperwork and ID to prove it!), and I feel entitled to go wherever a woman my age is entitled to go and do whatever she is entitled (and capable) to do. Grocery shopping, shopping around at a local mall, going to a movie theater. . . all ages are usually present and you just have to accept that fact in advance if you’re going to be in those places and live a normal life.
I am pretty sure I do not fully “pass” 100% of the time, in all places and with everyone with whom I rub shoulders. But, to judge from others’ reactions to me thus far, in all the places I’ve been as a woman, if I am not taken to be a born woman, then I either look and act acceptably enough to be treated as a regular woman, or else I am simply not “interesting” enough to make any big deal about. Any of those three reactions suits my purposes.
