I think of Asperger’s as being a little like internal bad eyesight.
Your view is always just slightly obscured by some kind of self-generated fog. You can make out the blurry body, faint borders, looming shadow of social existence, sure – you won’t stumble past the thing clueless. But you’ll always need the assistance of some external entity to really see clearly.
Of course, when in a familiar environment, you can attempt to orient by making use of prior experience. You can recall patches of prickly conversation and tread carefully in their midst. You can remember that what seems [on your] right might be sinister to another, and not in the Latin sense of the term. You can mentally map past broken social scenes, begin at their beginnings again, and this time move slower – and grope the air more – to ensure that you steer clear of problem areas.
Typically, however, strategize, squint, and feel around as you might, you end up tripping over something stupid.
