"'Ginny listen...I can't be involved with you anymore. We've got to stop seeing each other. We can't be together.'
'It's for some stupid noble reason isn't it?'
'It's been like...like something out of someone else's life these last few weeks with you. But I can't...we can't...I've got to do thigs alone now. Voldemort uses people his enemies are close to. He'salready used you as bait once, and that was just because you were my best friend's sister. Think how much danger you'll be in if we keep this up. He'll know, he'll find out. He'll try and get me through you.'
'What if I don't care?'
'I care. How do you think I'd feel if this was your funeral...and it was my fault...'"

"'Seventeen, eh!' said Hagrid as he accepted a bucket-sized glass of wine from Fred.
'Six years to the day we met, Harry, d’yeh remember it?'
'Vaguely,' said Harry, grinning up at him. 'Didn’t you smash down the front door, give Dudley a pig’s tail, and tell me I was a wizard?'
'I forge’ the details,' Hagrid chortled."

'So he can sneak up on people,' said Ron. 'Sometimes he gets bored of running at them, flapping his arms and shrieking...'"

"You'd think people had better things to gossip about," said Ginny as she sat on the common room floor, leaning against Harry’s legs and reading the Daily Prophet. "Three Dementor attacks in a week, and all Romilda Vane does is ask me if it’s true you’ve got a Hippogriff tattooed across your chest."

"I told her it's a Hungarian Horntail," said Ginny, turning a page of the newspaper idly. "Much more macho."
