In "Lonesome Dove" by Larry McMurtry, a light-hearted moment unfolds between two characters, Deets and Augustus. Deets is overcome with laughter at a joke or thought he finds amusing, slapping his leg in delight. This contagious joy attracts the attention of their fellow companions, who eventually come down from the house to see the scene. Together, Deets and Augustus share a grin that indicates their mutual enjoyment and camaraderie.

Augustus comments on their interaction, likening it to a child's excitement over discovering something new, such as teeth. This metaphor reflects the innocent joy and amusement that the two characters experience in each other's company, adding a layer of warmth and playfulness to the narrative. This moment captures the spirit of friendship and the simple pleasures that can be found in everyday life among a close-knit group.
