Vampires and Rapunzel

                   Today is a test of my resolution to write every day.  After a ten hour shift worked on five hours of sleep, I am finally writing something.  With the help of my wonderful boyfriend, who has been pestering me to quit being distracted by webcomics and work on my blog post, of course.
                   He says I should write about vampires, but I don't really have any ideas for vampires - not so much as a character quote or story concept.  I don't like working with a subject that has been done so many times unless I feel I have a unique twist to add to it.  And while I may personally hate the Twilight conception of vampires, I do have to admit that Stephanie Meyer at least gave an old idea a new life.
                   Lately, I feel that most of my best ideas have to do with reinventing classic fairy tales.  For instance, what would happen if Rapunzel was actually a spoiled teenager, and not the innocent captive so typically portrayed?  How does it change the story, and the characters, if the moralities are reversed in that way?
                   The first problem I run into with this concept, is that I don't know how to write a spoiled teen without making her sound like a child.  Every attempt I have made to script this Rapunzel, even just in my head, makes her sound about six years old.  Since I imagine that this would probably be a third-person perspective following Rapunzel, that makes her speech a crucial part of the story.
                   I also don't know the setting.  Is it a classic medieval fantasy setting, or a more modern one?  If I attempt a modern (or even science fiction) fairy tale, how do I incorporate the sense of isolation that is so crucial to the storyline?  In our ever more connected world, how can that isolation be anything but illusory, and how can the character of the prince fail to notice it?  But in a classic fantasy setting, the prince should be able to spend five minutes with Rapunzel and decide that she's not worth rescuing, causing him to ride off on his white horse and never return.
                   With a little luck, I'll glean some of those answers from Charles Dickens' Great Expectations, the book I am reading right now.  The character of Estella is not dissimilar to the Rapunzel I want to create, though unlike Miss Havisham, the "witch" character should not actively encourage Rapunzel's worst qualities, simply fail to curb them.

.                  .                 .

                   And with that, my train of thought has reached an abrupt end of the line.  Perhaps tomorrow I will have more to say on this subject.  Or perhaps I will end up talking about something completely different.
