In "The Children's Book" by A.S. Byatt, a heartfelt exchange reveals a deep affection between two characters. The speaker expresses love for Florence while asking if she will maintain her sensible nature. This highlights a tender vulnerability in their relationship, as the speaker seems to rely on Florence's rationality.

Florence's response takes a lighthearted turn, acknowledging the inevitability of becoming "silly" with age. This reflects a universal truth about human nature, suggesting that as people mature, they often embrace less serious, more whimsical aspects of life. The dialogue captures the warmth of their bond while also hinting at the complexities of growing older.
