Prev t/pdoc has an office in my apartment building, so I run into him (or almost get run over by him) fairly regularly. Usually it's barely a nod, he's often on the phone. Sometimes i'll initiate a very short conversion.

I ran into my old work T from ten years ago just yesterday at the local art fair! We hugged, i told him about PC. It was great to see him!

Current t, I have seen a few times outdoors, and each time we became exponentially more familiar. To where next time, I think I will be able to just act normal

my actual brother, who is a T, used to have an office near where I once lived. I was out for a walk, saw him in his parking lot, waved and called his name. He got mad at me, he was worried about how his patients would react to seeing their T interacting with a crazy woman. Duh.
