“ ...If only Dad hadn't cheated. If only Mom had found a way to be happier. If only Nina hadn't run away. If only I could deal with it better. 'If' and 'only' are the two most useless words in the human vocabulary, Dr. Hakim had made a habit of saying. They should never be used together in a sentence, because they speak of something that's beyond your ability to change. A waste of energy. ”
