Professor Trelawney looked like a cross between an enormous bug and a carnival huckster. Of course, that's exactly what she was. At that moment, she was staring at Hermione with anger flashing in her magnified eyes, but for some reason Hermione couldn't muster the appropriate amount of chagrin. Certainly, if Professor Flitwick or Professor McGonagall looked at her in such a way Hermione would be mortified. Yet, she couldn't possibly care less, not even when Professor Trelawney spoke.
"I am sorry to say that from the moment you have arrived in this class, my dear, it has been apparent that you do not have what the noble art of Divination requires. Indeed, I don't remember ever meeting a student whose mind was so hopelessly mundane."*
There was a moment's silence. On either side of Hermione, Harry and Ron sat mutely, looking as if somebody had just flicked them on their noses. As for Hermione, she felt relieved. In fact, yes! Giddy. She felt positively giddy. She'd hated Divination from the start, stubbornly keeping at it because she was no quitter. But fortune telling was rubbish, and now she was done with it.
"Fine!" She got up and crammed her textbook into her bag. It really was grand actually. "Fine!" she said again. "I give up! I'm leaving!"**
Liberation! Hermione would keep her dignity, she would not run to the exit even though that was exactly what she wanted to do. Run out of this stifling room, run through the halls of Hogwarts shouting her freedom from the top of her lungs. But no, she would make a decorous departure. Once she was out of sight she was going to find a nice cupboard where she could burn her blasted Dream Diary.
Then, maybe she would indulge herself a bit. Find Cedric Diggory's class, nonchalantly wait in the corridor until he got out just so she could catch sight of him. After months and months of killing herself with twelve classes, trying to save a hippogriff, and keeping Harry from being murdered again, Hermione rather thought she deserved a treat.
