Well I'm not post op but I do understand what you mean.
I have these moments at times (rare, as I'm not even out yet)
Like today, I went for a bike ride on a fairly busy trail, I was just another run of the mill female. I only interacted with a few people and it was short but I was not trans to them (although to my self I still know I'm trans).
I have seen my transition reach different milestones, ones I haven't even set for my self but heard of others achieving and then noticing it happening to me.
Passing (ugh hate that word) is of such importance, many will say it doesn't matter, what matters is if they are accepted as them selves. Thats fine but I want to be accepted as female. It seems though to other trans if you say this or if this is happening then they think your an elitist. If being accepted as just another woman while shopping, doing yard work, biking, attending events and ...........makes me feel like I am achieving my goal, then I am an elitist. I already know for a fact that the people that knew me as (ugh him) will never see me as just onother women.
I've read over your post at least 3 times, I have tried to read something other then what was written, but I'm not to good at reading between the lines.

I'm sure someone will see something though.
