It’s 18:50 on Friday evening at London Paddington train station. There are people and queues everywhere, and where there are no people and queues there are bags and bikes and dogs and boxes. There are literally thousands of bodies and objects and idiots like me, walking around with no idea where stuff is or which way to go.

Amoungst all this madness a blind couple just swanned straight through the station. Holding white sticks in one hand and with their arms locked around each other they walked through as if nobody was there. The guy looked determined, the girl was grinning from ear-to-ear and they bumped into absolutely nothing.
