Daunting task

Can you imagine the difficulty of the task Anne Sullivan undertook when she agreed to try to teach Helen Keller? The child was not only blind, but deaf, which meant that she basically had never communicated to any meaningful extent in her entire life. And yet I recently saw a video in which Sullivan was teaching Keller to speak, even though she had never heard speech, by having her place her fingers upon her throat and face as she spoke, to learn how the larynx and breath operated.
