He suspects that's how he lost his last job, am I correct ATM?

Sounds like an interesting job.  With any luck you'll be able to effect some helpful shifts in attitude.

I have to agree that if God made autism for a reason it's most likely introspection and free thinking.  And it's very important to have quiet time alone, but I honestly have no idea how you would teach that need to children.  There was certainly never any need to teach it to me.  It's probably a good thing I missed out on exercises to teach proper socialisation too, it would just have made me miserable.

It's true that lots of people have difficulty understanding spectrum body language.  However, I actually prefer it that way; it makes me very uncomfortable when other people are aware of what I'm thinking and feeling at any given moment.

I'm surprised to hear you have no stimmers in your group.  I'm in a gifted school and there's at least one of us in pretty much every class there.
