Cremolafoam... your post could have described me at a similar age, and younger. I had a dreadful time at primary school, because all I wanted to do was read, and found other children a bit of an anathema - used to spend much time on the sidelines 'observing'. When I wasn't hiding somewhere with a book to get a bit of peace and quiet.
Also used to come out with some shocking things before I learnt to prefer silence at around 9 or 10.
It was in the days before 'labels' were given to behavioural issues and I was variously described as 'odd' through to 'hysterical' and pretty much everything in between.
As I got older I learned to modify my behaviour and fit in better with others, but it really wasn't until I was the back end of senior school that I really 'found' my way. General consensus from those that knew me at the time was that a higher than average IQ can sometimes make things quite difficult for a kid.
I found solace in music, art and books and still do. Orchestral work allowed me to be part of a group which didn't rely on conversation exclusively and where a degree of 'oddness' was more par for the course!
I now mostly pass for normal ? well... as normal as anyone... Have had a good career, married, functioning etc...
TBH though I'd still often rather read a book than have a conversation... I just don't TELL...
