Robinhood & Peacehaven
My junior year of college I took a class on English literature during the Victorian era. One discussion I remember in particular centered on the role of the Tube, London's underground train system, the first in the world, which opened during said era. Suddenly you could descend into the ground at one place and pop up somewhere completely different. Great change happened from one simple action. In our discussion we concluded H.G. Wells and other English writers were heavily influenced by this concept.
I am reminded of that class every time I go through a carwash. It's only 20 feet or so of relative darkness, but change happens. Dirty becomes clean. Dusty becomes shiny.
Sigh. I miss college.
