@clacke that's not too dissimilar to myself. On my mother's side of the family there have always been a lot of brilliant people, a lot of odd people and a few who had obvious differences from "normal".
My mother has a cousin who is autistic and developmentally delayed. Since that was my first experience with Autism, that is what I thought Autism was when I was younger. It never occurred to me that it could apply to me until I was an adult and began some serious self reflection.
