Not far from City Hall, water falls through metal gates into an area in which is is collected only to evaporate, so it does not bother those who go underground to not be hit by the water from above… and the water evaporates and it moves back up through the gates and eventually it comes back to the same location, just to evaporate again. Or is it different water? It certainly is different water… but the area was created to collect the same water… the water that comes in through the metal gates… and it always does… well, when it rains it does… and it always rains… only the amounts vary…
and so things are much more similar than they are ever different…
even if all that happens is subtle or not so subtle change.
