" Alice didn't like being criticised, so she began asking questions. "Aren't you sometimes frightened at being planted out here, with nobody to take care of you?" "There's the tree in the middle," said the Rose: "what else is it good for?" "But what could it do, if any danger came?" Alice asked. "It could bark," said the Rose. "It says ‘Bough-wough!' " cried a Daisy, "that's why its branches are called boughs! "
