Cycling home this morning I came across a couple of p&ds setting up an extension ladder against a house wall. The road was slightly uneven so they'd placed a wooden wedge under one leg. Here's t'thing - the wedge was fitted with the blunt end towards the house and t'sharp end facing into the road. This looked weird - the leg was already at an angle as the ladder was leaning against t'wall, but having the wedge this way made the leg's contact angle with the slope even more severe than if it were contacting the road itself. Chust didn't look right. Surely having t'wedge t'other way would have the ladder leg sitting 'square' on the wedge's slope? I approached the two guys and said "Tell me to mind my own business, but shouldn't that wedge be t'other way around?
