Told by Ann Gargan and Rita Dallas, Rose Kennedy faced the nurse bravely and said, "We'll be all right." But she really didn't want to be with them. She didn't want to see anyone just then. Her room was too small for the pacing she must now do, and rubbing her elbows she said to Ann, I’ll be outside." Leaving them weeping, the President's mother, the most religious of the Kennedys, went down to the lawn by the sea, to stride back and forth throughout the remainder of the afternoon, a solitary, graceful figure walking over mile after mile of autumnal grass while her invalid husband slept.
