I’m old enough to remember the day itself – I was a trainee lawyer in London and we watched the news unfold on a conference room television – which means I am also old enough to remember the world before it. But a quarter of a century on, it is taught in schools as a historical event. Can you believe it? No, because if you experience such a convulsive moment – even at the distance of being a television viewer in a different country – time bends around it and normal chronology becomes meaningless ever after. But that is only our perspective.
