More than probably any other relationship, the parental one is fraught with more ritual and little touches. All the trappings of childhood -- the toys or diapers or swing-sets or braces or car seats or playclothes -- are far more involved and continually used than the toybag or dungeon of even the most ardent BDSM'er. And the role of parenting is filled with nearly endless "ritual", from bedtimes, story-telling, potty-training, discipline, schooling... to learning to drive -- it never ends.
But some of those icons of parenting can be very subtle, too. How touched can a parent be to find an old finger painting in a box, to notice the bronzed little shoes on the mantle for the first time in years... To tack that one report card on the fridge because, although it's nothing more than a slip of paper, and meaningless to anyone else, its presence reminds them of something very special about their life whenever they see it.
