For Irene nothing beat cleaning for peace of mind. Scrubbing the floor, attacking a closet, ferreting out the grime wedged between the lip of the stovetop and the counter with a butter knife filled her with a sense of calm and purpose. But here in her new home on the south side of the brand new assisted living facility there was no dirt, no smudges or even dust bunnies. She looked out the window, studied the endless blue sky for one day, two days, three days. On the fourth day she left her mop, pail and rubber gloves beside the recycling bins and signed up for a trip to the mall.
