Had two nice encounters today:
First, I was at the indoor spaces of a playground with my children. After some hours there, a six-year-old asked: "Are you a boy or a girl?", to which I said "neither one really. A little bit more a girl than a boy, but not really either one."
"But then why do you look so much like a woman if you are not a woman?"

(The child has no idea how warm and giddy that made me! My voice is the deepest male voice I know among my social circle, but my clothing and accessory style is that of a woman. Haven't really felt as female as I'd want to, but apparently there's more female to my appearance than I had really thought)

And then I was walking towards home with my children and learned that there's a trans-dar just like there's a gaydar. I'm bi enough to have a largely functioning gaydar and the searching signal and response seem to work in the same manner.

In any case, I was guessing she's probably trans, and let the transdar do its magic to be sure. And after that I read a lovely greeting from her lips, to which I gestured a friendly greeting back. And then we continued our ways, me towards the bus terminal, she away from it.

First I had my first experience of passing, which is nice. Even if on a very easy level. And then, under half an hour later, I learned that I'm a part of a more tight-knit community than I had really understood. It felt meaningful for a random stranger to turn out to be a friend.
