“Your children are not here to fill the void left by marital dissatisfaction and disengagement. They are not to be utilized as a substitute for adult-adult intimacy. They are not in this world in order to satisfy a wife’s or a husband’s need for love, closeness or a sense of worth. A child’s task is to fully develop his/her emerging self. When we place our children in the position of satisfying our needs, we rob them of their childhood.”
—Aaron Hess (20th century)
