Dora's exaggerated claim that David is now a "poor laborer" is another indication of her naiveté. In Dora's mind, there is little difference between the kind of work David is doing and that of a working-class laborer, probably because the idea of needing to work at all is foreign to her. In any case, Miss Mills' attempt to explain the situation to David hinges on the idea that Dora is not cut out for anything that requires effort or practicality, because she is too childish and delicate—or, as Miss Mills puts it, "a thing of light, and airiness, and joy."
