“Professor Umbridge left Hogwarts the day before the end of term. It seemed that she had crept out of the hospital wing during dinnertime, evidently hoping to depart undetected, but unfortunately for her, she met Peeves on the way, who seized his last chance to do as Fred had instructed and chased her gleefully from the premises, whacking her alternately with a walking stick and a sock full of chalk. Many students ran out into the entrance hall to watch her running away down the path, and the Heads of Houses tried only halfheartedly to restrain their pupils. Indeed, Professor McGonagall sank back into her chair at the staff table after a few feeble remonstrances and was clearly heard to express a regret that she could not run cheering after Umbridge herself, because Peeves had borrowed her walking stick.”
