The quote from Sophie Kinsella's book "Finding Audrey" captures the overwhelming realization that comes with awareness of the vastness of humanity. It suggests that often, we may not fully grasp the sheer number of people that inhabit the world around us. This notion can provoke feelings of anxiety and stress, especially when one is sensitive to social interactions or unfamiliar situations.

Kinsella's work often explores themes of mental health and the challenges of social anxiety. In this context, the quote serves as a poignant reminder of how confronting the realities of social life can be daunting. It encourages readers to reflect on their experiences with the crowds and their own inner feelings about connection and isolation.
