You’re right about the poster. I suspect I’m also somewhere on the autistic spectrum; I don’t know where honestly, although from a young age I always found Autism fascinating and relatable [at the time, Autism was limited to people who would probably _never_ be typing on the Internet, alas, but it was expanded in 1993 when they realized it was a spectrum issue].
I’ve had Aspie friends tell me that I’m Aspie. I’ve had other people say that I act/talk like an Engineer. I scored great on all things in school except, “What is the author’s intent?” – I never understood the mindreading they expected me to do.
