In a station of the metro

It's an odd sensation when the only thing keeping you upright on the metro is the fact that people are jammed so tightly together that there is literally no other option than to be, well, upright.

At one point I caught myself holding my breath and scrunching my face with my eyes firmly shut. When I opened my eyes, I caught the man, whose armpit my head was a quater of an inch away from, looking at me as if to say "Pfff, amature."
