The train is so loud and noisy

Metal on metal, screeching with a regular irregularity, as the rail cars rush on by, metal tracks, metal braces, metal hitchs, metal wheels. You cannot stop the train with your hands, you can only step away.

And as you back away, internally, from  ---- your own internal cerebral energy, you notice the painting on the box cars, the colors of the graffiti, on most of the train cars.

That graffiti may be your own verbalizing, the words in your head, and your words, about your intent, your life.  Those words--- are as effective as that paint on wood and metal, is
in determining the train engine.
