The story begins with George Hadley and his wife discussing sending a psychologist, not a technician, to look at the Happylife Home system. So right away, Ray Bradbury sets up the idea that this Happylife Home system is more than just a computerized nursery. Bradbury suggests that this nursery has a mind that needs a psychologist to look at.
When the Hadleys do call a psychologist, he discusses the nursery as if it was a person as it had "the usual violences, a tendency toward a slight paranoia here or there..."
In addition, the psychologist calls the room the children's "mother and father, far more important in their lives than their real parents."
When the Hadleys shut off the Happylife Home, George says, "...the whole damn house dies as of here and now." This comparison of shutting off something electronic to humans doesn't end there. The narrator says, "The house was full of dead bodies, it seemed. It felt like a mechanical cemetery."
