The quote from Rick Riordan's "The Red Pyramid" illustrates a character's humorous perception of her sister. The imagery of the sister's unconventional appearance—ratty hair, linen pajamas, and combat boots—suggests a carefree and rebellious nature, which contrasts sharply with the serious idea of being possessed by a goddess. This contradiction highlights the character's skepticism and adds a touch of levity to the narrative.

Through this quote, Riordan captures the essence of sibling dynamics, where one might see the other's quirks and question their significance. The mention of the "goddess of chewing gum" further emphasizes the light-hearted tone and the playful dismissal of grand themes in favor of family humor and relatability. It sets the stage for the adventurous yet whimsical tone that permeates the story.
