No one seems to have mentioned it, so I thought that I should remind everyone that the bombs, which killed 52 people here in London, exploded a year ago. Thankfully, the day has (so far, at 6.45pm) passed peacefully. The two minutes' silence was well-observed. The best thing about today, though, was seeing everyone going about their business and using all forms of public transport. That's the best way to give the terrorists the finger.
