“ Your grandfather was a hero in a war, girls. He wasn't a bad man or a weak man. Maybe he was too old to have a second family, a second wife and your mother and me, so many years after he lost his first. Maybe he was too old to fight anymore, and that's why he let me be taken away. I've thought about this for years and years. All I know is there are no heroes in this world. Not really. Just men and women who become old and tired and lose the strength to fight for what they love any longer. ”
