pecking order
Today I watched a van try to pull in front of a tram - normally the sort of event that causes tram to loudly slam on their brakes and voraciously ring their bell. This time it didn't happen. The tram braked normally and when the driver of the green beast had noiselessly attracted the attention of the van, he suggested that the van pull back a little way to make room. A very oddoccurrencee indeed, but I'm holding back on some of the information - the van was from the electricity board, the IWB.
Now obviously the tram is still the king, but this respect for other city servicemen is something I hadn't before spotted. All that's left to figure out now is how to use this knowledge in my never ending conquest to try to take over the world.
