"Dad took moving pictures of us children washing dishes, so that he could figure out how we could reduce our motions and thus hurry through the task. Irregular jobs, such as painting the back porch or removing a stump from the front lawn, were awarded on a low-bid basis. Each child who wanted extra pocket money submitted a sealed bid saying what he would do the job for. The lowest bidder got the contract."
