"Every choice we make allows us to manipulate the future. Do I ask Adrienne or Suzanne to the spring dance? Do I take my holiday on Corsica or on Risa? A person's life, their future, hinges on each of a thousand choices. Living is making choices. Now you ask me to believe that if I make a choice other than the one found in your history books, then your past will be irrevocably altered. Well, you know, Professor, perhaps I don't give a damn about your past, because your past is my future and as far as I'm concerned, it hasn't been written yet."
