Of all the characters in either a story from a book or in a movie, I know that I identify closely with "Rose" in the movie
Titanic - mostly because of her social disposition (i.e., she was from a once well-to-do background, she's torn about being married - which she knows to do so is for all the wrong reasons, and because she's full of life and feels like her life will end if she keeps doing what her mother wishes for her to do) and how she actively chooses to live her life with purpose and defy social conventions of her day.
She's strong willed, feisty, sassy at times, funny, warm, sensitive and certainly an intellectual of her own accord - all things that I feel are aligned closely with who I percieve myself to be.
