The quote illustrates the concept of an inner voice or consciousness that everyone possesses, yet remains elusive until a pivotal moment. The kid's defiance in claiming he hasn't heard it highlights a common human tendency to dismiss deeper truths or insights until they become unavoidable. In this context, the dialogue between the kid and Tobin suggests that awareness of this voice is intrinsic to the human experience, even if it often goes unrecognized or unacknowledged.

Tobin's assertion that one will realize they have been hearing this voice all their life once it finally stops indicates a profound connection to one's own existence and choices. It underscores the idea that personal revelations are an inevitable part of life, where the consequences of one's actions may lead to an overwhelming revelation of self. The conversation not only reflects on the nature of perception but also on the existential journey a person undertakes in understanding their place in the world.
