I'm new to the Twilight series and I'm only about 1/4 of the way through the first book. I really like the plot, but I'm having trouble buying Bella's character. She is supposedly suppose to be very mature (like helping her mom keep up with things, cooking for her dad, ditching school dances). If all that is true, why does she act like a dramatic kid with Edward? It drives me nuts. If she is so mature, then she would take his picking at her with face value and just realize it's flirting rather than storming off and slamming doors. I was just curious to see if anybody else had noticed that too??? Also, thanks in advance for your answers, but no spoilers please.

(Also, if you answered this in the books category you can just ignore this, I wanted to try it in another category so that I can get more answers,thanks.)
