In this quote from "Don Quixote" by Miguel de Cervantes, the speaker defensively claims to be sober, attributing their current state to the absence of breakfast rather than intoxication. This line implies a deep sense of inner turmoil, highlighting a struggle with guilt or moral failing, as they reveal that their only companion is their 'sins.'

This poignant statement reflects the themes of self-awareness and the psychological battles faced by individuals. In a broader sense, it underscores the human condition, where one's vices can overshadow the mundane aspects of life, like the simple act of eating breakfast, indicating a deeper existential conflict.
