What do the Kellers want Annie to do? What did they want Annie to do about Helen
In the broadest sense, they want Annie to teach Helen to behave, and, along the way, to give them some sort of a break. Individual Kellers want more at various times in the play; it depends on when we're talking about and how much they believe Helen capable of. They don't really think that Helen can learn as much as she does, and they don't necessarily think that teaching manners and limits is part of it, but they come to appreciate these things along the way.
