Annie was a miracle worker.
Explanation:
- Annie was confident and she motivated Helen Keller. She taught her hand symbols for various objects. But Helen felt it as a repetition game and did not respond well.
- Helen misbehaved with Annie as she could not express her emotions. When other family members treated Helen like an infant, Annie treated her like an ordinary child with disabilities.
- Once she pumped water on her hands to show Helen how it would look like. This brought an amazing change in the life of Helen Keller.
