Great post on The Realistic Autistic, A Hostile World on the way the senses are often affected in people on the spectrum:

I wish more people would be that thoughtful about their interactions with others.  Most people have no way of knowing these difficulties I’ve described, and so I’m “reclusive” or “hard to get to know” or “unsocial.”  But most days it’s a trial to go out for any reason.  If even a tenth of the people I normally deal with understood that, my life would be a lot less anxiety-inducing.
