In "Long Way Home" by Katie McGarry, the dynamic among the characters is vividly illustrated. The metaphor of Pigpen and Dust as "human cement pillars" suggests their staunch loyalty and solid presence in the protagonist's life. This imagery captures the essence of friendship, highlighting how some friends are unwavering, providing support even in challenging situations.

The line implies that even if the protagonist faced adversity, Pigpen and Dust would be there, symbolizing strength and reliance. Their steadfastness could inspire confidence, suggesting that true friends are not only present in moments of success but also stand firm during struggles, reinforcing the theme of enduring companionship throughout the narrative.
