I remember where I was on September 11, 2001.
Sitting on a park bench in a London suburb enjoying a quiet day off. An elderly couple nearby were exchanging greetings with a park gardener. I wasn’t eavesdropping, but did overhear one phrase being repeated: “We’re lucky here. Look at other countries on TV, they have buildings falling down.” Until I got home, I thought they were talking metaphorically.
