Valli dreamt of riding on the bus. Her eagerness to fulfill her dream fired her curiosity. This curiousness led her to listen to the conversations of the people going on the bus ride and asking discreet questions so that she could gather as much information as she can regarding the bus journey.
On the bus journey, Valli acted confidently and behaved maturedly. She did not consider herself to be any less than an adult. She was focused on fulfilling her dream and did not get tempted to go outside the bus and explore the town when the bus reached the town. On the return journey, she learnt about death when she came to terms with the dead cow. This made her aware of the fact that death is a part of life and should be accepted as it is a natural phenomenon. Thus, the bus journey made her learn a lot of things.
