““The thing that is maybe the real difference, the fundamental difference, is that in adult literature you can have a literature of despair and end the work without any hope; you can have a literature of the absurd in which life is pointless, meaningless...In children's literature you can have a tragic ending...nevertheless, maybe what happens makes some kind of sense; maybe there is hope. We have got to pull out of ourselves some kind of hope. This is the key difference between writing for adults and children.””
