In the book "Sentinel" by Jennifer L. Armentrout, a character addresses the unusual behavior of two individuals who communicate telepathically, suggesting that it is considered impolite to do so in the presence of others. This moment highlights the importance of social norms and etiquette in their world, where such abilities can create divisions or misunderstandings among those who may not share the same powers.

This quote reflects a broader theme of connection and isolation in the story. The use of telepathy can deepen relationships between those who share this ability but can also alienate others, emphasizing the characters' struggles with their identities and the complexities of their interactions. It serves as a reminder of the need for transparency and openness in relationships, especially in a world filled with unique challenges.
