‘And what good’s theory going to be in the real world?’ said Harry loudly, his fist in the air again.
Professor Umbridge looked up.
‘This is school, Mr Potter, not the real world,’ she said softly.
‘So we’re not supposed to be prepared for what’s waiting for us out there?’
‘There is nothing waiting out there, Mr Potter.’
‘Oh, yeah?’ said Harry. His temper, which seemed to have been bubbling just underneath the surface all day, was reaching boiling point.
‘Who do you imagine wants to attack children like yourselves?’ enquired Professor Umbridge in a horribly honeyed voice.
‘Hmm, let’s think…’ said Harry in a mock thoughful voice. ‘Maybe… Lord Voldemort?’
Ron gasped; Lavender Brown uttered a little scream; Neville slipped sideways off his stool. Professor Umbridge, however, did not flinch.
