I had my transdar go off at a club a few weeks ago. My friends and I were chilling on a sofa behind the dance floor, just enjoying the moment and each other. My eyes were wondering around, enjoying the scenery when I caught sight of this tall girl dancing like maybe 40 feet away. I noticed some of her features when my transdar went off. I just knew. I stared at her for about 15 seconds, because I was reading her, but mostly I just wanted to go up to her and greet her. Say what's up to someone like me. She then noticed me and knew that I knew. I felt kind of bad since she probably saw me as another cis person staring at her. I just wish there was a way to approach other trans people in public without outing them. We really need to develope a way. Maybe a secret handshake lol.
