The Serpent's Shadow question

I actually really like Sadie. I'm from America, and I've never really found her annoying. You'll see on the internet that most British people just find Americans odd or plain crazy. And I think sibling competition is the most natural thing in the world! They'll always think they're better than each other.

Well this is odd... Sadie is my favourite character! Are you from america? Because personally I find that the sort of attitude she displays there is found amusing throughout most of England.... And I don't think she thinks she's better than carter I just think she is naturally cocky and carter is a quieter person.... I think the difference between them just shows the contrasts in their upbringings.
