Because it was on that day - the day before Christmas Eve - that the dunny man made his solitary mistake.
My mother and I were having breakfast. I heard the dunny man's footsteps thumping along the driveway, with a silent pause as he hurdled my bicycle, which in my habitual carelessness I had left lying there. I heard the usual thumps, bangs and heaves. I could picture the brimming pan, secured with the special clipped lid, hoisted high on his shoulder while he held my mother's gift bottle of beer in his other, appreciative hand. Then the footsteps started running back the other way. Whether he forgot about my bicycle, or simply mistimed the jump, there was no way of telling. Suddenly there was the noise of... well, it was mainly the noise of a dunny man running full tilt into a bicycle. The uproar was made especially ominous by the additional noise - tiny but significant in context - of a clipped lid springing off.
While my mother sat there with her hands over her eyes I raced out through the fly-screen door and took a look down the drive-way. The dunny man, overwhelmed by the magnitude of his tragedy, had not yet risen to his feet. Needless to say, the contents of the pan had been fully divulged. All the stuff had come out. But what was really remarkable was the way none of it had missed him. Already you could hear a gravid hum in the air. Millions of flies were on their way towards us. They were coming from all over Australia. For them, it was a Durbar, a moot, a gathering of the clans. For us, it was the end of an era.
