“Malfoy swaggered forward when his name was called and got his wish at once: the hat had barely touched his head when it screamed, ‘SLYTHERIN!’ Malfoy went to join his friends Crabbe and Goyle, looking pleased with himself. There weren’t many people left now. ‘Moon’ … ‘Nott’ … ‘Parkinson’ … then a pair of twin girls, ‘Patil’ and ‘Patil’ … then ‘Perks, Sally-Anne’ … and then, at last – ‘Potter, Harry!’ As Harry stepped forward, whispers suddenly broke out like little hissing fires all over the hall. ‘Potter, did she say?’ ‘The Harry Potter?’ The last thing Harry saw before the hat dropped over his eyes was the Hall full of people craning to get a good look at him. Next second he was looking at the black inside of the hat. He waited. ‘Hmm,’ said a small voice in his ear. ‘Difficult. Very difficult. Plenty of courage, I see. Not a bad mind, either. There’s talent, oh my goodness, yes – and a nice thirst to prove yourself, now that’s interesting … So where shall I put you?’ Harry gripped the edges of the stool and thought, ‘Not Slytherin, not Slytherin.’ ‘Not Slytherin, eh?’ said the small voice. ‘Are you sure? You could be great, you know, it’s all here in your head, and Slytherin will help you on the way to greatness, no doubt about that – no? Well, if you’re sure – better be GRYFFINDOR!”
