F train. Going downtown. Train has the old layout. I grab a seat next to the window. People on the platform moving with Brownian motion. Random, yet not. The train starts moving. Suddenly those people seem stationary. Everything is relative. One day life seems to be moving the other day, it is at a stand still. But is it really one or the other? Or is it like the people on the platform? Stationary yet moving. How can one tell? Darkness. We enter the tunnel.
