It is night. The cover of clouds is thick enough that perhaps the sun has given up trying to get through. The air is cool, the seabreeze has lost most of its brine. Manhole covers ooze with steam. Cars are driving, slowly, just following the path of least resistance, and most green lights. Underneath, clockwork ticks and clicks and hums.
Something gets bored. In turn, something else clicks.
It is night, and the buildings are made of cold, dead rocks and brittle clay. There are faces in the windows, but not behind them.
All the lights turn green and shine.
