妈妈总是说人们对孩子太担心。她说，年轻时会遭受痛苦。它可以免疫您的身体和您的灵魂，这就是为什么当我们哭泣时她忽略了我们的孩子的原因。她告诉我们，对哭泣的孩子大惊小怪。这是负面行为的积极加强。
(Mom always said people worried too much about their children. Suffering when you're young is good for you, she said. It immunized your body and your soul, and that was why she ignored us kids when we cried. Fussing over children who cry only encouraged them, she told us. That's positive reinforcement for negative behavior.)
