I was 39 when I had the eureka moment, when I discovered that not every message is said directly, that some messages are coded using certain words but intending to mean something totally different. Eg: "I've been busy", "what do you do for a living?".
It took me another 10 years to gradually discover how crucial the above discovery is for interaction with humans, how massive non-verbal communication actually is and, as a result, that there was a whole world right in front of my eyes I'd been blind to for 4 decades.
Along the way, by force of analysing words for hidden intent, I discovered commonalities among humans, and this led me to read that there is such a thing as Theory of Mind that makes NTs know all of the above intuitively without needing eureka moments after decades of self-and others-search.
I was in my late forties when I learned how to use all this a bit to my advantage, eg. in order to delay some the inevitable being fired from jobs.
What stood between me and a bit more control over my life was just the knowledge of a fact: there's such a thing as the non-verbal. What if I'd stumbled upon this little piece of information at age 8, or 16, or 22 or 31? How would my life have been different? In this sense, what is it like to be a young aspie in the WrongPlanet era?
