I can't be sure, of course, but I'd compare it to living on tofu and soy milk; we call ourselves vegetarians, our little inside joke. - Edward Cullen
In this quote, Edward Cullen humorously reflects on his existence as a vampire, likening his diet to that of a vegetarian who consumes only tofu and soy milk. This analogy highlights the irony of calling oneself a vegetarian while strictly adhering to a limited diet that excludes meat. It serves to depict Edward’s struggle with his nature and the choices he makes, presenting a playful yet poignant insight into his character.
Moreover, the inside joke about vegetarianism underscores the complexities of Edward's identity. Though he identifies with a lifestyle that suggests he embraces life, the reality of his vampire nature sets him apart from normal human experiences. This contrast between self-identification and true nature emphasizes the themes of longing and the desire for a life he cannot fully partake in, adding depth to his character in "Twilight."
