I didn't say it was!Ah okay.
ADHD isn't the opposite of autism. I don't think anything can possibly be opposite to autism - not even Williams syndrome or Downs syndrome, because saying that's the opposite to autism suggests that autistic people are all aloof and unsociable, which isn't the case for all of us. Besides, Williams syndrome wouldn't be called that if it was just a highly extroverted personality, so it's obviously a disorder and people with it probably do have social challenges even though they are seemingly socially extreme. For example they might just go up to anybody and start talking and not notice that they're annoying or intruding, or it could make them vulnerable to predators, that sort of thing.
Also I'm more ADHD than autistic.
The opposite of 'my condition', I said!

In certain ways the way my mind works is opposite to how hers does. Whether that's to do with ASD or ADHD doesn't matter and I couldn't say, only that she shares some of my gene's.
