The controlled explosion at the Gare du Nord just after noon on Saturday was loud enough to sound as if it wasn’t controlled, but when nothing happened – shards of glass from the roof of the train shed did not fall on our heads, the station was for a few seconds absolutely and reassuringly silent – everyone carried on as if nothing had happened. I was on my way to lunch with friends before the rugby at the Stade de France – France v. Italy. The explosion was mentioned briefly at our table, then swiftly forgotten.
