I know that there exist classes aimed at people with social anxiety disorder; these often do teach many of the same things that autistics need to learn, socially.
I wonder if there are classes aimed at people who need to learn practical skills, like me and the bus system, or paying bills, or cooking, or... y'know, all those little things the NTs just seem to pick up. I know they teach them to people with mental retardation, but I think many of those classes take place in special ed at school, and that's probably not something we could just join if we weren't under twenty years old.
