1. The controlling boyfriend
2. That electrifying stomach butterfly
So this is pretty much in the first book exclusively, but it's when Edward and Bella don't quite touch, and it's described as an electricity between the two. I remember that intensity, when you're so attracted to someone that their very proximity is like an electric charge up and down your skin that makes those insidious butterflies in your stomach set flight. And when you do touch? It's like you're on fire. This was one thing Meyer actually wrote really well. I kind of missed it in the rest of the books.
3. The puppydog
|That tattoo is on the wrong side. Yes, I watched the movies too|
I think everyone has had their puppydog. Bella literally did. Mine was John. While I bounced from man to man, I watched and tried to pretend he was just my friend and that it didn't make him jealous, all the while spending as much time in my presence as possible. The puppydog isn't a bad thing, after all, I chose mine, the eventual end of our relationship notwithstanding. Sure, the puppydog can become a bitter person, like Jacob Black, but only if they're toyed with.
So there you have it. Three reasons I found Twilight relatable, I think these three may be the most widely encompassing, but like I said, it's subjective.
