Desmond Tutu tells a story of when he was nine or 10 years old and he stood with his mother outside a building where she worked as a cook. This was 1940s apartheid South Africa, where black people were considered inferior in all respects. A lanky, white Anglican priest named Trevor Huddleston walked by in a long cassock, saw his mother, and doffed his hat to her.
The white man would have been expected to ignore the black woman, who amounted to nothing in her society. With one simple gesture, he went out of his way to tell her that her society had it all wrong and that she was equally valued and loved.
That moment made a profound impression upon Tutu, who wrote about it in his book, Made For Goodness.
What seem like very small, ordinary acts often have immense and lasting impacts. And every interaction that we have — even with a stranger on the street — can leave some sort of mark, either helpful or hurtful.
