You should have told her differently,' said Hermione, still with that maddeningly patient air. 'You should have said it was really annoying, but I'd made you promise to come along to the Three Broomsticks, and you really didn't want to go, you'd much rather spend the whole day with her, but unfortunately you thought you really ought to meet me and would she please, please come along with you, and hopefully you'd be able to get away more quickly? And it might have been a good idea to mention how ugly you think I am too,' Hermione added as an afterthought.'But I don't think you're ugly,' said Harry, bemused.Hermione laughed.
