In showing Beth’s fear and genuine physical deterioration, the book underscores how vulnerable Beth is and suggests that her addiction is a dangerous, potentially fatal illness rather than a moral failing. Beth’s fear is well-founded, particularly after Mrs. Wheatley’s death from alcoholism. Her situation is another example of how addiction can be cyclical: Beth drinks to cope with loneliness, but drinking also makes her less likely to reach out to others, further entrenching loneliness.
