Trashed elbow

I have recently become alarmed by the tendency of folk to mimic the actions of those around them without really thinking about it. I'm inclined to blame the tendency of the Japanese to walk around with their noses in their phones without paying attention to such mundane inconveniences as, oh, say: traffic.

I have but to stick a foot into the busy junction and some adjacent pedestrian will register my movement and decide it's safe to start crossing the road without taking their eyes off the e-mail they're typing, red man or no.

I'm going to end up getting someone other than myself killed. Darwinism in practice, I guess.
