Communication is a big deal in Twilight. Edward is accustomed to reading minds, but when he's unable to do this with Bella, he doesn't know quite how to communicate with her. They have to form a new communication style, which involves asking each other tons of questions and reading each other's body posture, facial expressions, and tone of voice. Bella even judges Edward's mood by his changing eye color. Communication is especially important in this inter-species relationship. Bella and Edward both have different communication styles within their families as well. Bella tends to keep secrets from her parents, while Edward and his family share everything.
