why is annie frustrated when her two weeks of being isolated with helen comes to a close? (miracle worker) and what does the incident at water pump prove about annie's beliefs?
She's frustrated because her work has just begun. Helen is spoiled and the family have made so many allowances and accomodations that they are just enabling her to remain in an isolated world. Annie understands this and is attempting to break through years of depravation. In those two weeks she's made some breakthroughs but nothing like Helen's father wants to see. The incident at the water pump proves that Helen can learn and is not mentally deficient.
