My ex likely qualifies as ASD, though he was never diagnosed. He is terrible with faces. Faceblindness is common among ASD individuals. He had a lot of other issues.
He was career military. A common recommendation for ASD individuals is to let them wear the same stuff over and over, to get them multiple copies of their favorite items to wear. Wearing the same thing helps accommodate their sensory issues.
In the military, he was required to wear a uniform. He had multiple copies of it. A lot of people who have to wear a uniform get tired of it. It's boring. It's stultifying. But ASD individuals find it a comfort.
He didn't have to remember faces. Everyone's last name was displayed on their uniform.
He had handwriting issues, probably dysgraphia. He had his favorite pen. As an adult, he didn't need a file giving him permission to use a particular writing instrument to accommodate his issues. He had choice and it was chalked up to personal preference.
If we happen to find a situation that's a good fit for how we are, we look competent and brilliant. If we are expected to do things that don't work well for us, performance suffers.
There's really nothing magical or mysterious about that. It's just a shame we so often require people to have justification for their preferences.
