For a long time nobody spoke; then a Clam said, "What a difference there is in mothers!" It quite startled the Sticklebacks to hear a Clam say so much. It showed how interested he was, and well he might be. The Clam who brings up children has to do it alone, and be both father and mother to them, and of course that is hard work. It is hard, too, because when a little Clam is naughty, his parent can never say that he takes his naughtiness from any one else.
