Youngsters eventually discover what the wise have known for millennia: people rarely commit single sins. Thievery and lies and lies about lies, macho pride and mockery and assault, laziness and snappishness and cheating, and alcohol abuse that empties back into laziness —these sins and products of sin keep on replicating and bunching together like clusters of grapes on the vine. The clusters show up in individual persons but also in groups (in family systems, for instance) and in the places where groups and individuals meet. Hence the corruption of persons, of communities, and of whole cultures.
