The quote suggests that individuals often present a facade to the world that conceals their true emotions and struggles. It highlights the discrepancy between outward appearances and inner realities, emphasizing that people might seem fine or confident on the surface, while they deal with hidden pain or insecurities beneath. This theme resonates in Katie McGarry's "Crash into You," where characters grapple with their personal challenges despite how they are perceived by others.

The book illustrates this idea through its protagonists, who face various internal conflicts. As they navigate their relationships and external pressures, the narrative reveals that understanding someone truly requires looking beyond their outward behavior. McGarry effectively portrays how each character's journey involves confronting their hidden selves and overcoming the barriers created by their projected images.
