Im out for a walk round a local housing estate. Im wearing a graphic t shirt a blue denim jacket and tight grey jeans. Ive 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 thats 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
