wild horses to the more ambiguous "Wild Things", a term inspired by the Yiddish expression "vilde chaya" ("wild animals"), used to indicate boisterous children. He replaced the horses with caricatures of his aunts and uncles, caricatures that he had originally drawn in his youth as an escape from their chaotic weekly visits, on Sunday afternoons, to his family's Brooklyn home. Sendak, as a child, had observed his relatives as being "all crazy – crazy faces and wild eyes", with blood-stained eyes and "big and yellow" teeth, who pinched his cheeks until they were red. These relatives, like Sendak's parents, were poor Jewish immigrants from Poland, whose remaining family in Nazi-occupied Europe were killed during the Holocaust while Sendak was in his early teens. As a child, however, he saw them only as "grotesques". When working on the 1983 opera adaptation of the book with Oliver Knussen, Sendak gave the monsters the names of his relatives: Tzippy, Moishe, Aaron, Emile, and Bernard. Literary significance Analysis In Selma G. Lanes's book The Art of Maurice Sendak, Sendak discusses Where the Wild Things Are along with his other books In the Night Kitchen and Outside Over There as a trilogy centered on children's growth, survival, and fury. He indicated that the three books are "all variations on the same theme: how children master various feelings – danger, boredom, fear, frustration, jealousy – and manage to come to grips with the realities of their lives." Fundamental to Sendak's work for over fifty years is his trust in the validity of children's emotions. Dr. Kara Keeling and Dr. Scott Pollard, both English professors, assess the role that food plays in the book, arguing that food is a metaphor for Max's mother's love based on the idea that Max comes home to a "still hot" supper, which suggests that his mother "loves him best". Going along with this, Mary Pols of Time magazine wrote that "[w]hat makes Sendak's book so compelling is its grounding effect: Max has a tantrum and in a flight of fancy visits his wild side, but he is pulled back by a belief in parental love to a supper 'still hot,' balancing the seesaw of fear and comfort." Where the Wild Things Are is a story that shows children's resilience through their "spirit" and "pluck". Max is able to stand up to the Wild Things with their "terrible teeth" and "terrible claws"
