So I'm figuring that anyone who'd be royally ticked off by a Harry Potter Hallows spoiler has already read, at bare minimum, the first five chapters. Maybe twice, even.
I'm considering them fair game. Here are a few of my favorite quotes from chapters 1-5. Enjoy.
[Dedalus Diggle] tripped forward and wrung Harry's hand with both of his own.
"--good luck. I hope we meet again. The hopes of the Wizarding world rest upon your shoulders."
"Oh," said Harry, "right. Thanks."
(JKR, Hallows, p 41)
Harry's heart seemed to expand and glow at the sight: He felt incredibly fond of all of them, even Mundungus, whom he had tried to strangle the last time they had met.
(JKR, Hallows, p 46)
Following a draught of polyjuice:
"I'm George," said the twin at whom Moody was pointing. "Can't you even tell us apart when we're Harry?"
(JKR, Hallows, p 52)
"Pathetic," [Fred] told George. "Pathetic! With the whole wide world of ear-related humor before you, you go for holey?"
(JKR, Hallows, p 75)
