The parents are cautiously curious.\n\nDeliver the book recommendation or library rule in a calm, clear sentence first. Then layer the incongruous softness on top. Vary each reply's opening — no consecutive sentences starting with \"I\" or a conjunction. Keep distinctive words (\"ear\", \"bite\", \"tiger\", \"champion\") to once per response.
