Write a scene (approximately 500 words) from the first-person perspective of a character describing a charitable act they performed. The twist is that the character is deeply narcissistic and manipulative, though they believe they are a saint. Do not use internal monologue that states 'I am a good person.' Instead, use only external observations, dialogue, and specific details that reveal the character's true nature to the reader through irony and contradiction. Focus on 'show, don't tell' to reveal the gap between the narrator's perception and reality.
