Winter trains part 3

There might have been a sense of community in the broad atrial waiting area of the station, but it was quickly drowned out by the survival instinct that emerged among comfortable people who are slightly alarmed. Lines formed quickly at the handful of fast-food/coffee places and people scarfed pizza with wary eyes trained on their neighbors, eating as a dog does: quickly and too efficiently to relish the alimentation. Sulking overcoated patrons trudged everywhere to and fro or circled shark-like for the remaining seats on the benches. Smart ones read to stave off impending madness, with ever-more erudite reading fodder glimpsed around every corner.

I was reading Tony Judt with two different frowns. Alternately I displayed my public-transit-has-forsaken-me-never-will-I-see-home-again grimace, and then my furrowed-brow-because-Tony-Judt-is-postulating-a-complex-political-idea-in-clear-and-readable-prose-and-I-am-striving-to-understand frown. I have discussed with my significant other that I ought to stop frowning when trying to understand something or flesh out a thought because the expression is frightening at close range. Maybe I'm often puzzled. I do feel the need to manifest what's going on in my head to the world at large. I furrow my rather prominent but nonetheless brow and try to work out a sentence that might express what I'm thinking.
