I’m out for a walk round a local housing estate. I’m wearing a graphic t shirt, a blue denim jacket, and tight grey jeans. I’ve got my mobile phone handy in the top pocket of my jacket in case I come across anything interesting to photograph. My bladder needs emptying , so at the end of a street, I pass through a green iron gateway and into a playing field that’s behind the houses. A fence that separates one of the back gardens from the field gives me a tiny bit of cover, and I squat down and wet the ground through my jeans there and then. My jeans are soaked as I return to the estate. Will anyone notice the dark patch around my bum on my way back through?
