"Well if the lesson hasn't started yet I'll just go get something and be back in a minute. See ya". She left the classroom and ran to the great hall to get the the book she'd forgot to take with her when she'd left the hall after lunch.
She found it, put it back into her bag and hurried back to the classroom. When she saw that the professor hadn't arrived yet, she took a deep breath and sat down on a chair. She picked up the book again and started reading it.
