As I walk the lake today, all seems pretty dry and quiet—nothing too out of the ordinary. And just when I’ve almost returned to the car, in the parkland which once was golfcourse, which once was—or close to—rubbish dump, which once was…I notice the sound of the buzzing hum of hundreds, thousands, hundreds-of-thousands of bees above—and the white-coloured flowering of a big, broad, smooth-barked gum.
