“It’s nothing so sweet,” Mr. Shiftlet continued, “as a boy’s mother. She taught him his first prayers at her knee, she give him love when no other would, she told him what was right and what wasn’t, and she seen that he done the right thing. Son,” he said, “I never rued a day in my life like the one I rued when I left that old mother of mine.”
