we haven’t yet been told where the edges are
I love this bit also! I think that’s the answer to the question, “Why does the world always seem bigger when we’re younger”.
I think children possess an ability to think more freely, simply because they approach life without having been told what they can or cannot do yet. This is why each generation finds ways to expand life’s boundaries.
Therefore, children live in a world where their imagination can take them places that we, as adults (most of us), simply cannot go. The world is a larger, happier, and more natural place to live in. I wish we could all think like children sometimes 🙂
