Homework and a Good Book Open

Joey sat down at a table and pulled out his potions book, parchment and a quill, before dumping his bag at his feet. He was determined to get his homework done this time. Last time he had attempted it - in the study room - Peeves had come bursting in throwing opened bottles of ink around like water-balloons. Joey had been one of the few that had managed to avoid being splattered head-to-toe in black, inky stains.
He pulled his notes from potions class towards him and looked at the first question he had written down.
Please describe the rules of Potion class, and explain why they are important.
What were the rules of potions class? He had been told so many rules for different things in the past few days, he didn't know which rules belonged to what anymore. He cast his mind back, trying to focus on potions class specifically, before pulling an empty sheet of parchment towards him, loading up his quill and beginning to write.
Some time had passed before Joey looked up. He had finished the first, second and third questions and although nothing had distracted him, he felt his fingers needed a break from writing. Looking around, he could see quite a few people, although nobody was making much noise. Sir Nicholas, the Gryffindor House Ghost, was snoozing in an empty armcharir in the corner, although he kept sinking though it and waking himself up, much to his own annoyance. He looked down and read the next question, before picking up his potions textbook and looking at the index to find a suitable potion to use as an example.
Some time later, after breaking a quill and almost knocking over a bottle of ink,Joey finished his homework. Carefully making sure it was dry so he didn't smudge it, he put it in his bag along with his book and notes. Looking at the clock, he decided he must have been quicker than he tought doing his potions homework, as he still had an hour before dinner. He thought about looking at his other homework, before opting instead to pick a book from one of the many, many shelves and read. After walking past what must have been thousands of books, Joey settled on a green, pocket-sized, soft-bound, leather book - Beautiful Beasts of the British Isles by Newt Scamander. It looked like it very much pre-dated his famous Fantastic Beasts and Where to Find them. It claimed, on the inside page, to be copy 7 of 50, which made Joey wonder who had the privilege of owning the other 49 copies.
He wandered off between the bookshelves and found a soft-looking, faded-purple sofa, on which he could sit and read his book. Magical creatures had excited him ever since he had found out Unicorns and Dragons were real, and couldn't wait to see what else he could find.
