YMMV / Lazarillo de Tormes

• Accidental Aesop: The Blind Man savagely abuses his guide, who eventually turns on him and capitalizes on his blindness to make him pay. For such a wise character, it's bewildering that he is even surprised that this could ever happen. The resulting moral is one the author probably didn't intend: jerkassery is not always rational, and some people are such douchebags that they mistreat even those they depend on for dear life.
• Aluminum Christmas Trees: To many modern people, to find a black man portrayed sympathetically and in an almost color-blind way in a 16th century novel set in the Spanish Empire might be nothing sort of earth-shaking, especially given that Spaniards of the period carry the popular reputation of being essentially the Renaissance Nazis. In reality, racism would only appear two centuries after the novel is set, and due to the sheer intermarrying and mix of races that took place in the Spanish Empire from its very beginnings, it would never really catch on there.
• Audience-Coloring Adaptation: Sort of. Back in the 2000s, Spanish cheese brand Gran Capitán (named after the Great Captain himself) featured a popular series of ads that starred Lázaro and the Blind Man in situations typical of the novel. However, the ads featured wholly original stories and a Blind Man who was an Adaptational Nice Guy by an enormous margin, so people first exposed to the Lazarillo through them tend to be shocked when reading the book and finding the ad stories never happened and how cruel the old man was instead.
• Values Resonance: The novel features a black man in a mixed marriage whose race is never commented upon by other people (except for Lázaro and the man's son, who are children), and he is portrayed just as sympathetically as Lázaro and his mother. Historians have cited the novel as an example of how unexpectedly race-friendly Golden Age Spain was.
