Tisha

I've watched this film at least 2 dozen times, and one thing stood out for me more and more with each viewing. Tisha resented Libby. She was actually kind of cruel to her, from pulling the bowl of blueberries out of Libby's reach, to trying to get Sarah to send Libby away and come live with her instead. At the end of the film, I believe that Sarah finally understood this, and realized that she had to choose one or the other. She chose her sister. Did her friendship with Tisha end?
