Plot hole: When Annie Sullivan, as Helen Keller's teacher, gives Helen a doll that makes a sound, when they are alone in the small house, Helen upends the basket that holds all her dolls, but when the doll makes a sound, Helen grabs the doll and makes the sound the doll makes; but Helen is deaf, so how could she have learnt to imitate it?kh1616
Kate Keller: What happened?
Annie Sullivan: She ate from her own plate. She ate with a spoon. Herself. And she folded her napkin.
Kate Keller: Folded her napkin?
Annie Sullivan: The room's a wreck, but her napkin is folded. I'll be in my room, Mrs. Keller.
Viney, Keller Maid: Don't leave now, Miss Annie. Dinner'll be ready right away.
Kate Keller: Folded her napkin. My Helen folded her napkin.
