Linda's job places her firmly in the symbolic lighting of idealism. She sleeps during the disillusioning sunlight of broad day, awakens in the attractive dimness of the dream-ideal, and while in the blackness of subjectivity she "watches the light" (Monygham means that she tends it, but it's hard to avoid the image of her actually staring at it); i.e., she remains focused on the hope of true human communication.
