Valli's fascination with the bus reveals that she had a naturally curious and imaginative mind. For her, simply watching the bus pass was "every bit as enjoyable as any of the elaborate games other children played." This shows she could find joy in ordinary, everyday sights.
Her perspective reflects a childlike wonder — she noticed the changing faces of passengers each hour and found the bus a "source of unending joy." Rather than feeling bored by her limited surroundings, she turned observation into adventure, and gradually transformed her curiosity into a determined desire to experience the bus ride herself.
This reveals Valli as someone who sees possibility and excitement in simple things around her.
