"Oh, come off it!” said Edmund, who was tired and pretending not to be tired, which always made him bad-tempered. "Don’t go on talking like that.” "Like what?” said Susan; "and anyway, it’s time you were in bed.” "Trying to talk like Mother,” said Edmund. "And who are you to say when I’m to go to bed? Go to bed yourself.” "Hadn’t we all better go to bed?” said Lucy. –The Lion, the Witch, and the Wardrobe, C. S.
