 David! Look here, Father, Mother's right. Here's the place de la Concorde. Oh, shut up, Sorrel. Shut up yourself, you pompous little beast. Oh, you think you know such a lot about everything, and you're as ignorant as a frog. Why a frog? I give you my solemn promise, David, that you're wrong. I don't want your solemn promise, because I know I'm right. It's no use arguing with Father, Mother. Why is it any use arguing with Father? Because you're both so pig-headed.
