Stories aren't a "communication tool." Stories just are... we use communication tools to tell them.
Stories are powerful, no doubt... perhaps more powerful than any other element of learning. How they are told makes lots of difference. When we tell stories that are personal, true, emotional and purposeful, they take on meaning that moves people. Whether these stories are told through words, pictures, writing, sculpture, photographs, paintings whatever... the tool serves to represent the story, but the story is there regardless whether someone chooses to tell it or not.
