Professor Perry cleared his throat. "Alright, children. Thank you for your silence. Its nice to see that you are now able to hold your tongues when you are clearly wrong. I am your superior and it would do you good to remember that. Now... since you seem so fond of the Evanesco spell, why don't you try your hand at cleaning things up... the Muggle way? I'm rather disgusted with the state of this room. There are mops and buckets in the corner, as well as scrub brushes. Don't forget to get between every crack on the floor." |
