The character in "Funny Girl" by Nick Hornby grapples with an overwhelming sense of insatiability. This internal conflict is characterized by a persistent fear of her own greediness, as she feels unable to find fulfillment or satisfaction in her experiences. The desire to fill a void remains unfulfilled, leaving her with a sense of existential longing.

This sentiment reflects a deeper struggle that many face, where no matter how much they achieve or acquire, it never feels enough. The metaphor of nothing touching the sides emphasizes the depth of this longing, suggesting that true contentment is elusive for her. Hornby captures the complexities of human desires and the challenges of finding true satisfaction in life.
