We’re in Normanton, gulf country. It’s hot, dusty and dry. A million microscopic brown ants have taken roost in our van. I clean the caravan from top to bottom. Down on my knees scrubbing and throwing ant bodies into the rubbish bin and cursing. When all is done and everything is bright and sparkling again I turn on the coffee machine for a well earned break. There they are again waving tiny brown antennae at me…..we’re back! Just like the crocodiles they’ll be on this earth longer than us.
