“ What Caul liked most about Tom was his kindness. Kindness was not valued back in Grimsby, where the older boys were encouraged to torment the younger ones, who would grow up to torment another batch of youngsters in their turn. “Good practice for life,” Uncle said. “Hard knocks, that’s all the world’s about!” But maybe Uncle had never met anyone like Tom, who was kind to other people and seemed to expect nothing more than kindness in return. ”
