What you just said there has reminded me of something. A few weeks ago I was standing at the bus stop outside Denmark Hill station. The evening commuters, me included, were clogging up the pavement dressed in severe suits and scowling at the traffic as if staring a car down would turn it into a bus. A couple of kids walked by hidden under hoodies and as they passed I heard the one ask the other, ?Why do they always look so angry??
