Minerva walked a bit slower then usual to history of magic. It wasn't that she didn't like the class, but it wasn't one of her favorites. Her mind was everywhere else as well, so that wasn't helping. Thinking about the common room problem, this truth potion she had to give, some of the other odd lessons they had been having, it was all just a bit much. Then there was her personal life.. a small smile creeped across her face thinking about the boy she liked.

Then she stopped and looked around the room.. no teacher, no desks, no nothing.. "What's going on? We do have class today, right?" She wanted to make sure she hadn't missed a notice or something.
