I don't know. Maybe this is just reading induced psychohypochondria. I might just be making excuses. On the other hand I think that my behavior and my personal experience coincides pretty well with a very mild form of autism. I do stuff that other people just don't. I always eat the ice in a drink, whether at home or at a restaurant, and though if I consciously remember it I can avoid doing this it's just an urge I always get. I can spend many minutes at a time pressing my fingers into something sticky and peeling them off over and over and over, I love it, in fact there are stickers all over my house because of my doing this with just about every return label or anything else that gets sent my way. I shred paper subconsciouly, I always chew up popsicle sticks into woody pulp and I do a lot of other stuff that seems very much in line with the sort of repetitive simple behavior that autistics have. When I'm walking down the street I tend to focus inward and I don't respond to people calling my name for the most part, in fact I've noticed that I don't have much of a social smile, I have to sort of fake it.
I used to think of myself as just a loner but maybe it's more. The question then becomes should I seek treatment. The answer is I don't know.
Then again I've thought I was mildly dyslexic in the past because I tend to transpose letters and I often read stuff that isn't actually there. That's pretty common though, most high level readers don't finish words before they register and make mistakes for that reason.
