Minerva took the next book off the shelf. She twirled and pointed her wand "Mitisaura" the dust loosened and as it loosened some flew up into Minerva's face. She brushed it off, but it had put a tickle in her nose. She began to sneeze almost dropping the book. Minerva gripped the book harder and got control over her sneezing. "Sorry" she called down to the others in the office. She turned back to the book in her hand and pointed her wand "Tergeo" she watched the dust vacuum up. She put that book away and took out another one and then another one. "Mitisaura", "Tergeo". Finally she began to yawn. How long had she been working. Minerva climbed down and looked around. "Professor I think I'm going to stop for today and go get something to eat. I will be back tomorrow after my classes if that's ok." Minerva said her good byes and headed out of the office to the Great Hall.
