Well my theories are just that, theories. Adjustable with new information or even just new perspective. I notice with my autistic friends that the best thing I can do to keep them comfortable is to remain very still and quiet, and communicate as clearly as possible in nonjudgmental words. I know that they don't understand my body language, so I explain my mood and intentions to remove the mystery. It is an exercise for me in using words for things that I normally expect people to just "get". And it is fine.
