There’s a lovely interview between rob mclennan and Pattie McCarthy over at Touch the Donkey’s blog, in which she speaks a little about nulls:
Nulls mostly came out of my process of learning about autism— it is most definitely not about the experience of being autistic, because I don’t know what that is like— it’s about learning a new language, a new history, a new culture. I thought there was a sliver of space in which I could write that book, & I hope I successfully maintained that position throughout. Do I think there are ethical & empathetic ways to include the words & experiences & worlds of our children in our work? Yes. Do I always succeed in being ethical & empathetic about it? No. I know I do not. But I hope I treat them as worthy collaborators always.
