“Harry: This book belongs to Harry Potter. Ron: Shared by Ron Weasley, because his fell apart. Hermione: Why don't you buy a new one then? Ron: Write on your own book, Hermione. Hermione: You bought all those dungbombs on Saturday. You could have bought a new book instead. Ron: Dungbombs rule.”

“But Ron was staring at Hermione as though suddenly seeing her in a whole new light.“Hermione, Neville’s right — you are a girl. . . .”“Oh well spotted,” she said acidly.”

“You should write a book," Ron told Hermione as he cut up his potatoes, "translating mad things girls do so boys can understand them.”

“They were bullyin' him, Hermione, 'cause he's so small!" said Hagrid."Small?" said Hermione. "Small?""Hermione, I couldn't leave him," said Hagrid, tears now trickling down his bruised face into his beard. "See -- he's my brother!”

“Hermione launched herself forwards and started punching every inch of him that she could reach.'Ouch — ow — gerroff! What the — ? Hermione — OW!'“You — complete — arse — Ronald — Weasley!”She punctuated every word with a blow: Ron backed away, shielding his head as Hermione advanced.”

“Parvati positively beamed. Harry could tell that she was feeling guilty for having laughed at Hermione in Transfiguration. He looked around and saw that Hermione was beaming back, if possible even more brightly. Girls were very strange sometimes.”
