It is not blindness or deafness that bring me my darkest hours — it is the acute disappointment in not being able to speak normally. Longingly, I think how much more good I might have done if I had only acquired natural speech. But out of this sorrowful experience I understand more fully all human strivings, thwarted ambitions, and the infinite capacity of hope.
