The Mixed Blessing of a Man Who Killed His Grandmother With a Hammer

"It's one of those arthritis days. So my husband went off to church alone while I lay around feeling sorry for myself," she says. "A couple of hours later, when he returned, my spirits were suddenly lifted." She gives him a warm hug and shows him the paper shopping bag he set on the table. He pulls out his cell phone and reads me a news story about a man who killed his grandmother with a hammer.
