I love this! I'm autistic and so is my oldest son, neither of us diagnosed until well into adulthood. I was dagnosed at 48, my son at 30. Personally, I'm glad we went undiagnosed because I know my parents, and I know me as a young parent. A label, a diagnosis would have limited us, if that makes sense. I loved that my son was smarter than other kids and I loved his quirky personality, still do. And I just chalked up his sometimes "asshole-like" behaviour as not suffering fools gladly.
I was the same way, read early. Very bright. Very sensitive. I still remember the battles over turtlenecks as a kid, and clothing tags. My son an dI were both lucky, we had a few friends. I was very athletic, so never picked last on teams...you may have just sparked a story for me....
