Which character is known for wandering around gifting rotting vegetables?

The character known for wandering around gifting rotting vegetables is indeed Liesl. This peculiar behavior is emblematic of her eccentric personality and serves as a metaphor for her outlook on life, illustrating themes of unconventionality and the unexpected nature of human interactions in the novel. Liesl's actions often carry deeper meanings, challenging societal norms and expectations around relationships and personal identity.

In contrast, the other characters do not engage in such distinctive and symbolic behavior. Mrs. Dempster, for example, is more connected to themes of sainthood and the idea of a tragic figure within the community. Denyse represents a different set of values tied to societal expectations of femininity and relationships, while Diana's character focuses more on the exploration of romantic and personal relationships rather than the eccentric or transformative acts that Liesl embodies. Thus, Liesl's rotting vegetable gifts highlight her role as a catalyst for change and self-discovery in the lives of those around her.
