This morning Irma Kurtz did Something Understood on BBCRadio4 which she called Happy Accidents.  Having just woken up when it started I pricked up my ears and consciousness because I knew I had a book of hers downstairs called The Great American Bus Ride, which I had enjoyed very much, having traveled a few thousand miles on Greyhound buses myself back in the 1990s. When the programme was over I found my copy and sat with it over breakfast. After traveling with her for a few bus rides or so I found the receipt between the pages, from when I had bought the book. It was from Dillons in Oxford Street, 17 years ago in 1994, on 20th March, which is today’s date. Serendipity? Coincidence? Irma says this in the programme blurb:”Serendipity differs from mere coincidence – it doesn’t knock at the door and you can’t go out to look for it.”
