"If it's in the bin, it's public property" reflects a humorous yet insightful take on the concept of ownership and privacy. In Sophie Kinsella's book "I've Got Your Number," this idea plays into the story’s comedic elements, where characters find themselves entangled in situations involving lost items and the implications of claiming things discarded by others. The quote highlights how our perceptions of ownership can shift when dealing with forgotten or thrown-away possessions.

This notion encourages readers to consider boundaries regarding personal items and the extent to which we respect others' space. Kinsella uses this premise to explore themes of connection, miscommunication, and the humorous misunderstandings that arise when the lines of personal property are blurred. As characters navigate their various predicaments, the quote serves as a lighthearted reminder of the quirks of human behavior and societal norms surrounding ownership.
