In "Runaway," Alice Munro explores the theme of isolation through her characters who find themselves living in a unique world, detached from their surroundings. They inhabit a space where their interests and choices are not shared by those around them, creating a sense of curiosity about their solitude. This introspective isolation allows them to engage deeply with their own thoughts and passions, albeit in a way that seems disconnected from the community.

The narrative portrays these individuals as both curious and contemplative, subscribing to magazines that reflect their interests and tuning into radio programs that resonate with their inner lives. This engagement with media serves as a refuge, enabling them to experience a broader world while remaining physically isolated. Their happiness does not seem compromised; rather, it is a unique form of fulfillment that stems from their distinct perspectives and choices.
