i heard water running , and then i was dragged across the bathroom , the grooves between the tiles plucking at my hair and scraping my scalp , and then icy water sluiced down onto my face and chest , and i was trying to roll away , but the stream came from a handheld wand and i was sprayed down head to toe , and no matter which way i turned or rolled or how i curled up , the frigid water beat against my skin like knives of ice .
