Professor McGonagall said coldly, "Mr Ronald Weasley, you wish to know why you’re not the boy Prefect? Your marks in your classes are a disgrace to your House, your total lack of table manners disgusts your tablemates, and your unquestioning dislike of everyone in Slytherin would lead to open war between Slytherin House and Gryffindor House, were you a Prefect. Mr Longbottom, on the other hand, scores high marks, and when dealing with other students, he’s calm and thoughtful, whilst you are neither."
