THIS CITY IS JUST A VERSION OF YOU
I have no chance to get into other tram. They always run along red rails. All the trams are, actually, one single tram. All the cities are one single city.
I'm stepping into the existing footsteps. The footsteps are running away straight, they do not wave. Reflexively I move my foot but I am not moving an inch forward. The same accurate prints appear under my feet at the same very places. The footprints pattern coincides with the length of my step. I have walked here before, outrunning myself, have let myself behind. There is no chance to step away from this path...
