Temple Grandin once described herself as “an anthropologist on Mars,” a description that the neurologist Oliver Sacks appropriated as the title for one of his books. But Chris was like a Martian in a roomful of anthropologists. “In case he feels everything,” Bill said, “I talk to him about it all and I love him totally and completely. Just in case.” Is it neurotypical prejudice to posit that human nature entails an aspirational longing to be loved, applauded, accepted?
