In "The Little Prince," the fox shares a fundamental truth about relationships and responsibilities. He emphasizes that once we form a bond with someone or something, we hold a lasting obligation towards them. This is a reminder of the deep connections we create with others, which require care and commitment.

The fox's message about responsibility extends to the prince's affection for his rose. It symbolizes the idea that love and devotion create a lasting impact, and we must nurture what we cherish. Neglecting these bonds can lead to loss, making it essential to recognize and uphold our commitments.
