1. Lack of money: Lily and Rosaleen are practically penniless when they arrive in Tiburon. They have to be extremely careful with their money, and Rosaleen's illness adds an extra strain. Finding affordable food becomes a constant challenge, especially when Lily has to provide for both of them. This problem is highlighted when Lily finds a jar of peaches but has to choose between buying them or saving the money for a bus ticket.
2. Hiding their presence: Lily and Rosaleen are on the run from the law, making them reluctant to draw attention to themselves by seeking help from strangers. They are afraid of being found and forced to return to T. Ray, further complicating their situation. This leads them to scavenge for food in the woods and rely on the kindness of strangers like August Boatwright, who offers them food and shelter without asking too many questions.
Overall, their lack of resources and the need to remain hidden significantly influence how Lily and Rosaleen approach food. The challenge forces Lily to be resourceful and highlights the kindness of others in their journey.
