The quote from Larry McMurtry's book "Thalia: A Texas Trilogy" illustrates the unpredictable nature of love, particularly women's love. It compares love to morning dew, which indiscriminately settles on both beautiful and unpleasant things, signifying that affection can be given to both admirable and unworthy recipients. This comparison highlights the complexity and sometimes irrationality of romantic feelings, suggesting that love does not always align with merit or desirability.

By likening love to morning dew, McMurtry emphasizes that love often emerges in unexpected places, like a horse turd, reminding readers that emotions are not always rational. The quote reflects a broader commentary on the human experience, where love, in all its forms, is vulnerable to randomness and chance. It challenges traditional notions of love, urging a recognition of its inconsistency and the unpredictability of who deserves affection.
