I still don't like your tone, boy. If you can speak of your beatings in that casual way, they clearly aren't hitting you hard enough. Petunia, I'd write to them if I were you. Make it clear that you approve the use of extreme force in this boy's case.

'One can never have enough socks,' said Dumbledore.

"Harry — yer a wizard."

Wingardium Leviosa!' he shouted, waving his long arms like a windmill.

'You're saying it wrong,' Harry heard Hermione snap. 'It's Wing-gar-dium Levi-o-sa, make the "gar" nice and long.'

'You do it, then, if you're so clever' Ron snarled.

Hermione rolled up the sleeves of her gown, flicked her wand and said, Wingardium Leviosa!'

Their feather rose off the desk and hovered about four feet above their heads.

What happened down in the dungeons between you and Professor Quirrell is a complete secret, so, naturally, the whole school knows. I believe your friends Misters Fred and George Weasley were responsible for trying to send you a lavatory seat.

'Why me?'

'It's obvious,' said Ron. 'You can pretend to be waiting for Professor Flitwick, you know.' He put on a high voice, 'Oh Professor Flitwick, I'm so worried, I think I got question fourteen b wrong...'

'Oh, shut up,' said Hermione.

'There are all kinds of courage,' said Dumbledore, smiling. 'It takes a great deal of bravery to stand up to our enemies, but just as much to stand up to our friends. '

'Whatever house I'm in, I hope she's not in it,'

Humans do have a knack for choosing precisely those things which are worst for them.

Hermione's white face was sticking out from behind a tree.

'Harry — you're a great wizard, you know.'

'I'm not as good as you,' said Harry, very embarrassed, as she let go of him.
