My stacking and organization pushed boundaries. There were big, complicated patterns, difficult feats of balancing, or I tried to reach the ceilings. I never really endangered anyone, took their things, or created disturbances but was yelled at, even by the 'nice' teachers. They were allowed to use big, unusual words. I was criticized for it.
A library was within walking distance, at the top of the block, but there were only a limited number of non-fiction books, in the children's section. I wanted to know the names of things, and how they worked, particularly the plants and animals, which seemed more intricate, colorful, and complicated than anything in the Popular Mechanics books, at home. The librarians wanted me to read simpler stories, which I thought were for infants. I was allowed look in books, from the adult section, but not to check them out.
I tried to solve religious questions by testing them, so dabbled in spiritism, probably, at an unusually young age -- more along the lines of Tesla or Edison than Marilyn Manson -- but equally annoying to the atheist and Christian parent.
I was usually treated as though I was trying to be a little too clever with adults, or precocious. I was not especially trusted, yet could never be caught doing anything particularly wrong. My hearing seemed abnormal, I was lipreading, watching people's faces, when they talked. This seemed intense and made them feel uncomfortable. I had a visual memory of what was being said, and, on repeating it, was treated as though it was a trick, like I was trying to hold them to something.
