Also, the children in one part get really upset just for a couple hours. This shows that the children have become so hooked on this nursery that they can't even let it go for a couple of hours. Even when they know that they will get it back
eventually, and that it is not being taken away forever.
Finally, in the ending the children. Lock their parents in nursery with the lions, and the lions kill them. This shows that they love the nursery/technology so much that they will kill there parents just to have it. It also shows that they favor the nursery over there parents.
