Fun games autistics play:

‘Why is this person mad at me?’
‘Is this person mad because of me?’
‘Am I also mad at this person for possibly being mad at me?’
‘If I was this person, why would I be mad at me?’
‘This person wasn’t mad at me after all but why are they mad at me now?’

Yes, this is an autistic thing. Most of us struggle with cognitive empathy.

Cognitive empathy is the ability to understand how a person feels and figure out what they’re thinking. https://www.psychologytoday.com/us/blog/out-the-darkness/201705/is-autism-really-empathy-disorder
