"When I was about twenty years old, I met an old pastor's wife who told me that when she was young and had her first child, she didn't believe in striking children, although spanking kids with a switch pulled from a tree was standard punishment at the time.
"But one day when her son was four or five, he did something that she felt warranted a spanking — the first in his life. And she told him he would have to go outside and find a switch for her to hit him with. The boy was gone a long time. And when he came back in, he was crying.
"He said to her, 'Mama, I couldn't find a switch, but here's a rock you can throw at me.' All of the sudden a mother understood how the situation felt from the child's point of view: that if my mother wants to hurt me, it makes no difference what she does it with; she might as well do it with a stone.
"The mother took the boy onto her lap and they both cried. Then she laid the rock on a shelf in the kitchen to remind herself forever: never violence. Because violence begins in the nursery — one can raise children into becoming violent."
