I always enjoy talking to the elder gays, even though sometimes the men will be kinda inappropriate.
My favourite was this one old guy who came up to me while I was on a smoke break at work and immediately asked me "you're trans, aren't you?"
When I apprehensively said yes, he revealed he had transitioned in the late '80s! We had a nice little chat while I finished my smoke, he was really sweet and super proud of how comfortable the new generation of queers was being themselves. I definitely went into the bathroom to have a little happy cry afterwards.
