James P. Crow, by Philip K. Dick (epub/Kindle)
“You’re a nasty little—human being,” the newly-formed Z Type robot shrilled peevishly.
Donnie flushed and slunk away. It was true. He was a human being, a human child. And there was nothing science could do. He was stuck with it. A human being in a robot’s work!
He wished he were dead. He wished he lay under the grass and the worms were eating him up and crawling through him and devouring his brain, his poor miserable human’s brain. The Z-236r, his robot companion, wouldn’t have anybody to play with and it would be sorry.
