In Margaret Atwood's "Cat's Eye," the author presents a complex relationship between individuals, illustrating the duality of human interactions. At times, people can act as predators, causing harm and distress to one another, much like sharks. This metaphor reflects the hurtful behavior that can arise in friendships and social dynamics, highlighting how easily relationships can turn toxic.

Conversely, Atwood also emphasizes the importance of compassion and support, suggesting that people can serve as lifeboats, providing safety and comfort during difficult times. This balance between being harmful and nurturing captures the complexity of human relationships, showcasing the capacity for both cruelty and kindness in our connections with others.
