The arrival of Anne Sullivan as Helen's teacher marked a turning point in her life. Before Anne's arrival, Helen was isolated and frustrated, unable to communicate with the world around her. However, Anne introduced Helen to tactile sign language, using her hands to directly spell out words into Helen's palm. This breakthrough in communication opened up a whole new world for Helen, allowing her to express her thoughts and desires for the first time. With Anne's guidance and patience, Helen began to make incredible progress in her ability to communicate and learn. This marked the beginning of a remarkable transformation in Helen's life, as she found a way to connect with others and express herself in ways she never thought possible.
