My observation is that tango attracts an unusual proportion of neurodivergent people – probably because it has rules that encode social interaction (which they are often bad at, and need rules for) and because it has a deep vocabulary that can be understood via geometry and physics (which they are often good at, and find reassuring).
I had quite the trouble figuring out all the norms and unspoken códigos of the milonga in the beginning, until someone kindly pointed me to a few detailed blog posts here and there (Janis, Tango and Chaos, etc.), which jumpstarted the process.
When I was growing up, I had absolutely no idea what to do with other people, and so spent over a decade with painful trial and error and much stumbling over oneself before I learned the patterns. For me, it was a crippling inability to consistently and accurately interact with people in social situations that rely on understanding how they’re feeling, what they’re thinking, or what their expectations are from their facial expressions, body language, and nonverbal cues alone.
In essence, it's a massive never-ending stressful exercise in pattern recognition, which is why it is such a relief having all these things spelled out explicitly, in detail, and preferably covering every potential scenario or edge case.
I
think I have more or less internalised social interaction, but in the beginning it was very much an alien concept (but not for want of empathy).
Maybe it's worse or better for other people in a similar situation, but even now, at times, it still feels like I'm stepping out into the darkness, blind to everything that I might encounter.
