In Cormac McCarthy's "Outer Dark," a character reflects on the nature of solitude and communication. Living alone often leads one to converse with themselves, which can result in others thinking they're eccentric or mentally unstable. This highlights the fine line between sanity and the perception of it by society.

The character mentions that talking to a dog is more socially acceptable, even though dogs cannot comprehend human language or respond. This suggests a longing for companionship and the need for connection, revealing the complexities of human interaction and the ways people cope with isolation.
