Enhanced Pattern Recognition: What weird little thing did you pick up on before anyone else, and how?

I see this topic come up a lot with ADHD and I do not relate to it at all, but am fascinated. What weird little things have you noticed and how?

Disclaimer: there’ve been discussions about pathologizing “quirks” and applying them to ADHD as a whole which is so valid. We’re not X-men. But I just want to keep this thread fun and informative, and acknowledging the vast spectrum of ND. This won’t apply to everyone (myself included) and that’s okay!
