They had finally started work on Patronuses, which everybody had been very keen to practise, though, as Harry kept reminding them, producing a Patronus in the middle of a brightly lit classroom when they were not under threat was very different from producing it when confronted by something like a Dementor.
'Please, sir . . . why have the other centaurs banished you?'
'Harry Potter, you are a friend of Hagrid's, are you not?' said the centaur.
It was the most unusual lesson Harry had ever attended. They did indeed burn sage and mallowsweet there on the classroom floor, and Firenze told them to look for certain shapes and symbols in the pungent fumes, but he seemed perfectly unconcerned that not one of them could see any of the signs he described, telling them that humans were hardly ever good at this, that it took centaurs years and years to become competent, and finished by telling them that it was foolish to put too much faith in such things, anyway, because even centaurs sometimes read them wrongly. He was nothing like any human teacher Harry had ever had. His priority did not seem to be to teach them what he knew, but rather to impress upon them that nothing, not even centaurs' knowledge, was foolproof.;

He had just been forced, yet again, to relive a stream of very early memories he had not even realised he still had, most of them concerning humiliations Dudley and his gang had inflicted upon him in primary school.？
