In Terry Tempest Williams' book "When Women Were Birds," she explores the theme of voice and the selective nature of what is shared with the world. The quote "Not everything is meant for all to hear" emphasizes the idea that some thoughts, experiences, and truths are deeply personal and not intended for public consumption. This notion highlights the importance of protecting one's inner reflections and the sanctity of personal stories.

Williams delves into the complexity of women's voices and the cultural expectations surrounding them. Through her reflections, she invites readers to appreciate the power of silence and the significance of choosing what to reveal. The book serves as a meditation on identity, storytelling, and the intersections of personal and communal narratives, stressing that not all truths are universal or meant to be shared openly.
