Maybe it's because we don't confused time apart as a social cue for dislike?

Me too, actually. My late brother was autisic, and obviously so; enough that he got diagnosed in early childhood in the mid 1970s. He was a classic savant autist and a gifted musician. But given that ND tends to run in families, I wonder about myself too. I think maybe a little but not significantly. Same for my father. I've done a few self-tests and they usually come out a bit borderline.
