When I was young I did a few things that I spotted in tCIotDitN such as seperating food on the plate, and deciding if it would be a good day or bad day based on wierd criteria, my wife still hates the way I double-check any door I lock and take so long to clean anything or washup.
My Wife and mother in law both reckon I have difficulty with eye-contact and stuff and insist I always answer the phone or talk to people in social situations to improve it.
I don't get these problems in a professional context -- when at work I am a lot more confident and outgoing, even bossing people around in a way I would never do with family and friends.
my sister-in-law is the same, really shy at home but as a personal trainer in a law firm she wipes the floor with high-flying lawyers and managers.
I don't think I was ever close to having any actual medical problem but that could be because my family spotted problems early and still keep up the pressure to 'be normal'.
Oddly, the positions I am applying for at the moment are senior roles which involve a lot of the kinds of things my family would expect me to find hard but have never been an issue in the workplace.
Maybe its because in work environments I know how things are supposed to happen and have confidence in my experience and skills.
However, I suspect that if I had scored this test 15 years ago, I'd be much higher. (Not literally, but you know what I mean.)
Thank goodness I'm a recovering geek... I'm in a one-four-base-eight step program. It seems to be working.
