Little David Earl always knows what day of the week it is. He can tell by the clean, snappy-fresh apron Ma Dear is wearing -- a different color for every day. Monday means washing, with Ma Dear scrubbing at her tub in a blue apron. Tuesday is ironing, in a sunshine yellow apron that brightens Ma's spirits. And so it goes until Sunday, when Ma Dear doesn't have to wear an apron and they can set aside some special no-work time, just for themselves.
