And so rock bottom became the solid foundation on which I rebuilt my life.

Ron and Hermione were still smirking and Harry felt his temper rise; he wasn’t even sure why he was feeling so angry. “Don’t sit there grinning like you know better than I do, I was there, wasn’t I?” he said heatedly. “I know what went on, all right? And I didn’t get through any of that because I was brilliant at Defense Against the Dark Arts, I got through it all because — because help came at the right time, or because I guessed right — but I just blundered through it all, I didn’t have a clue what I was doing — STOP LAUGHING!

The sky was a cold iron-grey, like the underside of a shield. A sharp breeze lifted the hems of skirts and rattled the leaves on the immature trees; a spiteful, chill wind that sought out your weakest places, the nape of your neck and your knees, and which denied you the comfort of dreaming, of retreating a little from reality.

Once, long ago, Parminder had told Barry the story of Bhai Kanhaiya, the Sikh hero who had administered to the needs of those wounded in combat, whether friend or fo.

Dementors are among the foulest creatures that walk this earth. They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope, and happiness out of the air around them. Even Muggles feel their presence, though they can’t see them. Get too near a Dementor and every good feeling, every happy memory will be sucked out of you. If it can, the Dementor will feed on you long enough to reduce you to something like itself — soul-less and evil. You’ll be left with nothing but the worst experiences of your life.
