This is a truly fascinating video. It makes you think about the things we take for granted. I remember reading about Keller when I was a child. One story always stuck with me. Anne Sullivan struggled to teach Helen the word “water.” Anne put water in a cup and had Helen dip her hand in the cup. But Helen kept signing “cup”, not “water.” Finally, Anne ran Helen’s hand under running water. It clicked for Helen that Anne was trying to teach her the word “water.” Helen Keller wrote many books in her lifetime. Here was a woman who was blind and deaf and started out unable to speak. She became a well-respected author and one of the first advocates (perhaps unintentionally) for disabled persons. She remains an inspiration today and proved that even a disability can’t hold a writer down.
