Of course, I still saw Edward at school, because there wasn't anything Charlie {her dad} could do about that. And then, Edward spent almost every night in my room, too, but Charlie wasn't precisely aware of that. Edward's ability to climb easily and silently through my second-story window was almost as useful as his ability to read Charlie's mind.
In "Eclipse," Bella acknowledges that her father, Charlie, cannot control her interactions with Edward at school, where they frequently see each other.
