Change of Habit popped into my head at some point during The Curious Incident of the Dog in the Night-Time, not because the latter is even remotely awful, but because I wondered if, someday, The Curious Incident would seem as quaintly ridiculous and outdated as Habit is when it comes to its depiction of neurodevelopmental disability. I certainly hope so, not only because medical advances are a good thing, but also because I have a son on the autism spectrum, and I admit feeling frequently frustrated by how little anyone really knows about the disorder. During positive moments, though, I like to remind myself that, at the very least, we've left Elvis in the dark ages. As far as autism goes, we no longer resort to dumb, simplistic assessments involving real or metaphorical walls of anger. As we work toward answers, simplistic black-and-white dichotomies have given way to a lot more gray. There's something comforting in the gray. It's what we have right now. That's something.
