Hermione became so lost in her book, in fact, that she didn’t realize how much time had passed. When she finally looked at the clock, she was surprised to see it read 11:45 pm. She had been here nearly four hours already. Past my bedtime, she thought, and lightly chuckled to herself. She packed away her textbook, parchment rolls, and quills into her bag, and chuckled again at the sight: the bag looked as though it was about to split down the seams with so much crammed into it. She wished she could place an extension charm on her poor book bag, but the Ministry controlled that type of magic, so lugging around her half-broken sack would have to do for now. She did place a quick feather-light charm on it, though, so her shoulders wouldn’t suffer nearly as much heavy lifting.
