Before he turns off the nursery and many of the other electronic conveniences in the house, George Hadley speaks with his friend, Dr. David McClean, a psychologist, who tells George,
"You've let this room and this house replace you and your wife in your children's affections."
Further, he tells George that he and his wife have built their house around creature comforts. So, realizing what McClean has told him carries much truth, George turns off the electricity to the nursery, sending the two children, Peter and Wendy, into hysterics. Screaming, sobbing, yelling, swearing, and jumping at the furniture they cry, "You can't do that to the nursery, you can't!" When George says, "Now, children," they fling themselves onto a couch, crying. Peter looks up at the ceiling, begging the house, as though it were the parent.
"Don't let them do it!....Don't let Father kill everything."
Then, he turns to his father to express his hatred by saying "I wish you were dead." Clearly, Wendy and Peter are very spoiled and have become detached from their parents; instead they are engrossed in the action of their nursery which has become their world. And, unfortunately, it has absorbed the hatred expressed by Peter and Wendy, who later lock their parents into the veldtland.
This reveals the way the parents have spoiled there children! The children don't see there parents as a parents. They see them in the way and the house being there parents so that's why they loto them up.
