The sun has been blazing in the sky for days now. This morning is fine and the sun waxes in intensity as the hours draw on till noon. Groups gather on the scraggy banks of the Clyde to picnic on Red Biddy and its modern day equivalents. Boys, with no work and no school, congregate in the heat of the day, throw stones in the water and lie on the banks, their faces upturned to the sun.
On a promontory overlooking the gently flowing river, three 10 year olds strip down to their shorts and warily enter the stream, wading in to waist level and bobbing up and down in the waves created by a passing speed boat.
