“Mothers often are too easily intimidated by their children’s negative reactions...When the child cries or is unhappy, the mother reads this as meaning that she is a failure. This is why it is so important for a mother to know...that the process of growing up involves by definition things that her child is not going to like. Her job is not to create a bed of roses, but to help him learn how to pick his way through the thorns.”
—Elaine Heffner (20th century)
“It is often hard to determine whether a clear, open, and honorable proceeding is the result of goodness or of cunning.”
—François, Duc De La Rochefoucauld (1613–1680)
