In Haruki Murakami's novel "1Q84," the character grapples with the complexity of communication and the significance of unspoken thoughts. She feels that the essence of her feelings and the depth of her thoughts might diminish or be altered if expressed through words. This struggle highlights the fragile nature of human connection and the challenges of conveying true emotions.

Moreover, the quote reflects a broader theme of the novel, where characters often face isolation and the difficulty of sharing their inner worlds with others. Words can sometimes fail to capture the richness of human experience, leaving individuals feeling unheard or misunderstood. This idea resonates deeply with anyone who has felt the limitations of language in expressing profound sentiments.
