This is based on Helen Keller's memoir and play. One difference between the memoir and the play is that even though both the memoir and the play show that Helen treated her doll badly, only the memoir explains that she did so because she felt frustrated when she could not understand the reading exercise that Anne was teaching her.
It was also only the memoir that showed that Helen and Anne were frustrated with one another as a result of misunderstandings as Anne was attempting to teach her.
