I shared The Autism Society of America's status update.Thanks
  for sharing this. I think there are a lot of people walking
  around undiagnosed on the autistic spectrum. Inappropriate
  responses to non-verbal (or sometimes verbal) cues - like "How
  to react when surprised with something" - I've known a number of
  people who know the 'right' way to react and those who do not
  react 'appropriately'. And one side never really understands the
  other.^
