Someone said :
I have a brother who is severely autistic and the vast majority of people are very accommodating of him even when he's not behaving as an adult should. It's only really the odd very elderly person or someone from a country that isn't used to people like him walking about who react badly to him. Most of the time he gets spoiled where ever be goes from restaurants to A&E.
Maybe people who are in between ave the problem: not obvious enough to be spoiled like children, but to obvious to be treated with respect as adults.
