In the story "Black Sheep" by Georgette Heyer, a character expresses her frustration by comparing her futile attempts at conversation to speaking to a gate-post. This metaphor illustrates her feelings of hopelessness and isolation in trying to connect with someone who doesn't respond as she wishes. The quote highlights the theme of unreciprocated communication and the sense of despair that comes from feeling unheard.

Another character humorously remarks on her peculiar choice of conversational partners, contrasting the lack of reaction from a gate-post with the potential engagement of more lively creatures, like eels. This dialogue not only adds a lighthearted tone but also emphasizes the absurdity of her situation, making the interaction both amusing and reflective of the challenges of meaningful communication in relationships.
