We were somewhere unfamiliar, walking along a low bank of soil. There were four or five of us. The wall became a miniature mountain range. There were tiny houses and roads on its slopes. There were little towns and villages. We were giants, or had become giants or people were playing tricks on us. We argued whether we really were giants or we had walked into some kind of park and, on the other hand if really were giants, how long it would take us to circle the world on foot given our sizes.
