Have you ever imagined how an illiterate could feel? How powerless he was? How humiliating it would be to be on of the unfortunate people? What if in the same time, you were deaf and partially blind? What if the time period you were born in didn't have the hearing technologies that we have today? What if you were marginalized by the society you lived in? Wouldn't you do anything to be able to communicate again? Wouldn't you be willing to kill to have a normal life?
