New comic up...
Sam can focus and behave it seems, she just has to be in the right mindset to do so. With all due respect to the autistic spectrum claims, this to me is more and more confirmation that she's just easily excitable and overly enthusiastic about things that she likes and isn't obsessing over them, isn't diverting so much attention to them that she's neglecting everything around her, and isn't actively ignoring rules that go against what she's trying to do: she's just a kid with a lot of energy who has different interests.
Compare her with others who are known to be on or are more likely to be on the spectrum than her: Marigold, Hannelore, and definitely Brun. Sam just doesn't click all of the boxes that people want to put her in.
And by the way: ADHD isn't part of the autism spectrum. You can suffer from it and be autistic, but you an also suffer from it and not be autistic. My niece has both, my nephew is autistic. My younger nephew has ADHD. We hit the mother lode of behavior issues with them.
