In Jodi Picoult's "Perfect Match," the concept of building walls serves a dual purpose. Physically, walls can act as barriers that protect individuals from external threats or invasive forces. Emotionally, they can also symbolize safeguarding what we deeply cherish, creating a sanctuary for precious relationships and memories.
This duality highlights the complexities of human experience, where the act of building walls may stem from a desire to protect oneself or a loved one from harm. Ultimately, the quote reflects the intrinsic motivations behind our efforts to create boundaries in our lives.
