Tube Space

Standing today with the bum of a man much taller than me nestled into the small of my back a number of things crossed my mind. Firstly, that I could tell this was an irritated bum, how could I tell this? Something to do with the way it backed into me, like it was accusing me of getting in its space. Secondly, if it wasn't an angry bum it might be a slightly erotic situation. This thought quickly evaporated as someone's bag dug into me, the bum leaned angrily against me as the tube jerked and the doors opened to let more people on who will squeeze, push, cajole and inch a space out for themselves. And then London Bridge and the freedom of space and a depth of air that just doesn't exist in a tube carriage.
