I've always been very literal-minded, struggling to comprehend the reverse...and in 2013, I learned why. I was speaking with a caseworker while looking for a job, and they said I should go through a psychological exam. So I went, and after several grueling hours of testing plus a week of waiting for the results, they diagnosed me with a form of autism called Asperger's Syndrome. A good fictional reference is the character of Data in "Star Trek", who's locked into a personal quest to understand those around him, still feeling a separation he can't control. That's generally been what my mental and emotional nature has been like, for most of my life...and I recently celebrated my 44th birthday.
