“Then you will find yourself easy prey for the Dark Lord!" said Snape savagely. "Fools who wear their hearts proudly on their sleeves, who cannot control their emotions, who wallow in sad memories and allow themselves to be provoked so easily - weak people, in other words - they stand no chance against his powers! He will penetrate your mind with absurd ease, Potter!”

“Fools who wear their hearts proudly on their sleeves, who cannot control their emotions, who wallow in sad memories and allow themselves to be provoked this easily — weak people, in other words...”

“What would your head have been doing in Hogsmeade, Potter?" said Snape softly. "Your head is not allowed in Hogsmeade. No part of your body has permission to be in Hogsmeade.”

“Harry uttered an inarticulate yell of rage: In that instant, he cared not whether he lived or died. Pushing himself to his feet again, he staggered blindly toward Snape, the man he now hated as much as he hated Voldemort himself —“Sectum — !”Snape flicked his wand and the curse was repelled yet again; but Harry was mere feet away now and he could see Snape’s face clearly at last: He was no longer sneering or jeering; the blazing flames showed a face full of rage.

“If you choose to use your status and influence to raise your voice on behalf of those who have no voice; if you choose to identify not only with the powerful, but with the powerless; if you retain the ability to imagine yourself into the lives of those who do not have your advantages, then it will not only be your proud families who celebrate your existence, but thousands and millions of people whose reality you have helped transform for the better. We do not need magic to change the world, we carry all the power we need inside ourselves already: we have the power to imagine better.”

“You know how I think they choose people for Gryffindor team?" said Malfoy loudly a few minutes later, as Snape awarded Hufflepuff another penalty for now reason at all. "It's people they feel sorry for. See, there's Potter, who's got no parents, then there's the Weasleys, who've got no money - you should be on the team, Longbottom, you've got no brains.”

“His eyes are as green as a fresh pickled toad,His hair is as dark as a blackboard.I wish he was mine, he's really divine,The hero who conquered the Dark Lord.”
