“That's what they should teach us here. How girls' brains work… It would be more useful than divination, anyway…”

“Longbottom, if brains were gold, you'd be poorer than Weasley, and that's saying something.”

“Your devotion is nothing more than cowardice. You would not be here if you had anywhere else to go.”

“Hogwarts, Hogwarts, Hoggy Warty Hogwarts,Teach us something please,Whether we be old and bald,Or young with scabby knees,Our heads could do with fillingWith some interesting stuff,For now they're bare and full of air,Dead flies and bits of fluff,So teach us something worth knowing,Bring us back what we've forgot,Just do your best, we'll do the rest,And learn until our brains all rot...”

“Divination is turning out to be much more trouble than I could have foreseen, never having studied the subject myself.”

“It was strange how your brain could know what your heart refused to accept.”
