In Miguel de Cervantes Saavedra's "Don Quixote de la Mancha," a humorous admonition suggests avoiding garlic and onions. This advice is presented within the context of preserving one's personal image, as these ingredients are known for their strong odors. The statement implies that such smells may betray one's intentions or character, particularly in social interactions.

This reference highlights the broader themes in the novel concerning perception and identity. The character's concerns about how they are viewed by others resonate with universal human experiences regarding reputation and the ways individuals navigate social norms to maintain a certain image.
