The autism spectrum appears to be wide –
more nuanced than visible light.
While some demarcations are identified
I doubt that the shrinks have it right.

When Sally said neurodivergent’s the word,
I think Siggy tossed in his grave,
and Carl’s ghost suggested the notion’s absurd
while others mapped out a brainwave.

I saw a street placard referring a bit
to variance in sanity.
Omitting a letter was appropriate:
it read Neurodiverity.
