Experience. Autism runs in my family. Some have a mild case... with professional help they can do fine. Pros can give them effective cooping skills. Some are very serious, and all the professional help in the world just gets them to the point where they can go to the store and shop for themselves... they can't work... basically they are taken care of by other relatives. I have one cousin who has never said a word in his life, he has a very scheduled life, and when he deviates from his schedule he moans and walks around in circles.
got it. I know a lot about it. In my family also. It's a spectrum thing, some like you tell and others more high function. I am included, and one of my kids. Pretty common in software engineering circles. Together with a very smart professional, I taught the kid scripts. Most ppl now do not know when they first meet them. But later figure it out.
from the inside, it's like race. the person doesn't have a choice and we do the best we can.
when someone tells us to figure it out, our first question is how...
in the past no one knew, they just told that one is odd. I can now trace the behaviours into my ancestors and it fits.
it's growing in percentages for some reason. I would expect evolution (red queen theory) to remove it. But it's increasing in percentages, evolution is bringing it forward.
If all the social crap I have to think about was automatic like it probably is for you, I could do all sorts of things with the extra cycles.
I only recently (older..) learned how to interpret, process, and react to some things. It's just fascinating from a spectrum person on how things work and are simple. It's really fun, it's like someone removed the veil.
