The quote from Lonesome Dove by Larry McMurtry suggests a critical view of human conversation, implying that much of what people discuss lacks substance and significance. It highlights the idea that many words exchanged among individuals are trivial, akin to mere puffs of air, indicating that they may not carry true meaning or depth.

This perspective points to a broader commentary on human interactions, where the value of communication may be overshadowed by the superficial nature of many discussions. McMurtry seems to urge readers to reflect on the quality of dialogue in their lives and consider the impact of truly meaningful conversations.
