Quidditch
There was a general impression among the Weasleys that Hermione hated Quidditch. She had attended matches while in school, but as soon as she left Hogwarts it had been like pulling teeth to get her to watch a game.
The truth was, however, that Hermione didn't dislike Quidditch. She simply enjoyed having Fred give her the play-by-play after matches more than going to the games. Of course, had the Weasleys known Fred used Hermione's torso as a miniature pitch upon which to diagram the match's most exciting maneuvers they might have understood better her reluctance to sit in the stands.
