I was in a coffee shop a few years ago and a guy in line was wearing an O.G.R.E. shirt, a way old computer game from 1986.
I said "Nice shirt! Never played that game, though."
Completely delighted, he ranted about his love for the game until my order was ready. And it was a bit hard to get away from him afterward.
This is definitely someone who could've fallen into that category.
But I don't see it that way because I'm also neurodivergent and know people never engage with us like that. Might have made his day.
Just a little story from that borderline in the Venn diagram.
