-and the fact that Edward can't 'hear' her, which means she really is thoughtless--

LOL! I never thought about that! It makes perfect sense!

I always thought that all the author's attempts at making Bella look smart were just that, attempts. She never acted intelligently and all the focus on her 'great' literary mind were just there as window dressing. She read books that other people said were great and what was expected for a moody girl of that age. (Which, btw, I NEVER read at that age. Which is probably because I wasn't a moody teenage girl).

I like vampire books and I've read a lot of cheesy vampire romances but Twilight had the worst reasoning of them.
