"To jealousy, nothing is more frightful than laughter"

In this quote, Francoise Sagan is highlighting the destructive nature of jealousy. She recommends that jealousy is an effective emotion that can cause fear and anxiety in those who experience it. Making use of the word "shocking" suggests that jealousy is not simply a basic emotion, but rather something that can be terrifying and frustrating. Sagan likewise contrasts jealousy with laughter, which is often related to delight and joy. By saying that absolutely nothing is more terrible to jealousy than laughter, she is stressing the negative effect that jealousy can have on a person's feelings. In general, this quote serves as a suggestion of the devastating power of jealousy and the value of conquering it.
