However, I had another priority that year. I got the most wonderful opportunity I'd ever received, courtesy of McGonagall: A Time-Turner! True, I couldn't easily use it to set up alibis, because McGonagall knew I had it...but I got to practice and experiment to my heart's content. I honestly think I have more practical knowledge of the limitations and uses of a Time-Turner than anybody outside of the Department of Mysteries. Although I didn't use it to actually do anything Against The Rules (until the end of the year, and that was with Dumbledore's implicit permission) I did use it to snoop around at times when I was ostensibly in classes. As well as catching up on naps. I wasn't as worn out as I let McGonagall think by the end of the year; I had just come to the conclusion that Muggle Studies and Divination were both utter wastes of my time. I'll still sit the Muggle Studies OWL, of course---an OWL is an OWL, and I didn't get rid of the book. Divination just seems to be something for which I have no talent, and if Trelawney (or as I call her, "Tree-looney") is a fair sample of what Seers and Divination are all about, I've no worries on that score. Even the prophecies that are real are so cryptic that they might as well not have been made, so why worry?
