Thanks for the suggestion. I read all the pages available through Amazon's "look inside" feature, and also read Wikipedia on Asperger's and Autism, as well as browsed around on a couple of Aspie support sites.

I'm even less convinced now that I might actually have Asperger's or Autism -- for example, I have no trouble with metaphor or figurative language, I am very good at reading other people and subtle social cues (just can't do them myself), I've never had an obsession like collecting stamps or date calculating, I wasn't bullied ever and didn't have trouble understanding other children, etc. -- but I'm still puzzled by my high score. I think that perhaps extreme shyness and some anxiety issues, combined with having an intellectual bent in a world of mostly non-intellectuals, probably account for a good part of it.
