My wife always says bath time is her only pleasure, lingering in the tub and humming happily. Then my younger adult brother quits his job and moves in while searching for another. After his arrival, her baths become even longer. I assume the bathroom is simply the only place where she can be alone and occasionally remind her not to stay too long. It never crosses my mind that my brother is in there with her, their naked bodies entwined in an affair behind my back.
