"Harry, don't go picking a row with Malfoy, don't forget, he's a prefect now, he could make life difficult for you...""Wow, I wonder what it'd be like to have a difficult life?"said Harry sarcastically."

"Youth can not know how age thinks and feels. But old men are guilty if they forget what it was to be young."

"My Head of House said I lacked certain necessary qualities...like the ability to behave myself."

"Ask us no questions and we’ll tell you no lies."

"Why were you lurking under our window?""Yes - yes, good point, Petunia! What were you doing under our windows, boy?""Listening to the news,"said Harry in a resigned voice.His aunt and uncle exchanged looks of outrage."Listening to the news!

"Accio Brain!"
