[Bella:] "Charlie wasn't comfortable with expression his emotions out loud. I inherited that from him." (1.45)
Bella is uncomfortable expressing herself. This may be why she is distant with others at school and does not seem confident. However, she is almost immediately comfortable with Edward, and recognizes that about their dynamic. He gets her to reveal more about herself than she has to anyone else.

I didn't look up as I set my book on the table and took my seat, but I saw [Edward's] posture change from the corner of my eye. He was leaning away from me, sitting on the extreme edge of his chair and averting his face like he smelled something bad, inconspicuously. (1.149)
