Our attitude to sidewalks is affected by our point of view in time and space. Sidewalks serve to facilitate our movement over ground, and our relationship usually does not extend beyond walking on them; although we spend considerable time looking down, we do so only in passing.

Conscious of this insight we walk with heightened senses. The experience of this terrain is now twofold.
