Dorothy Whipple said this quote

It matters to ourselves, of course, but it matters terribly to other people. Moral failure or spiritual failure or whatever you call it, makes such a vicious circle... It seems as if when we love people and they fall short, we retaliate by falling shorter ourselves. Children are like that. Adults have a fearful responsibility. When they fail to live up to what children expect of them, the children give up themselves. So each generation keeps failing the next.
