My daughter came home from her job teaching autistic kids one day and said, "Mum, you've got Aspergers." I did the tests twice - 18 months apart. I'm quite high.
That said, I had a terrible childhood and most of my adult life was filled with extreme abuse. That could also account for it. There could be many different explanations.
Yes, of course being agreeable reduces conflict. I am seldom disagreeable. The people who had a problem with me are few and far between. They wrote about it. Apparently, there are a hundred articles about me on Medium, virtually all of them slamming me. And while I haven't defended myself, I can assure you that they were guilty of one thing or another.
You read my reviews. Those reviews are not the result of someone who is disagreeable.
