The Melvyns are uncomfortable and out of their element at Possum Gully, which is seen in their discomfort at living so close to other people. Sybylla’s sense of humor comes through as she muses about the pros and cons of having neighbors. Her conclusion is that other people are good to have around because they can help her, but they can be a nuisance when they require her help. This comedic selfishness signifies her immaturity.
