“Pity for this tyrant? Is there anything she wants she doesn’t get? I’ll tell you what I pity… that the sun won’t rise and set for her all her life, and every day you’re telling her it will. What you and your pity do will destroy her, Captain Keller. “
– Annie Sullivan (Anne Bancroft), The Miracle Worker (1962), screenplay by William Gibson, based on his stage play, based on the book by Helen Keller
this is one of my most favourite plays (and the movie version, as well). Helen Keller was a big inspiration for me (since I'm Deaf).
and the dialogue is just amazing, too.
