It could also be ADHD or a number of other things. I've noticed in the past 15 years that people tend to immediately armchair-diagnose anyone with slightly neurodivergent tendencies as autistic. I blame Big Bang Theory. I've only seen it a couple of times, but I think Sheldon is hinted as autistic in it and of course makes a big joke of it. Since that show was immensely popular, it put autism on many people's minds.

I'm not attacking your statement, and you could totally be right. But, it's my civic duty to chime in like some 70s McGruff knockoff and spout off my catchphrase-- "Remember, kids! There's more than one way to deviate from the norm! ®"
