Charlotte invents a dozen reasons for wanting a watch, and her inexorable parent disposes of them all, till she is forced back on Rousseau’s final position. A watch must needs be a _useful_ possession, since her Papa, philosopher as he is, cannot do without it. This, obviously, is a point to Charlotte. If she wants the thing for its _usefulness_, it is hers. The sudden capitulation is too much for Charlotte. She suspects her Papa of badinage. Not at all; he is perfectly serious. She will find the watch hanging from the tapestry by the side of his bed.
