I take the walk to be the externalization of an interior seeking so that the analogy is first of all between the external and the internal.
Most adults, unlike most children, understand the difference between a book that will hold them spellbound for a rainy Sunday afternoon and a book that will put them in touch with a part of themselves they didn't even know existed.
I'm a pessimist. But I'm a pessimist with a sense of responsibility.
