"To the Guy Who Teaches Before Me." From Dr. Amelia.
It's been my pleasure to follow your act three times a week this semester. I haul all of my stuff across campus to the room they assigned me. I find that you have, once again, not logged yourself out of the computer, but did leave it locked. It gets my blood pumping a little to once again figure out how I can access my files now. It's like exercise. Angry, bitter exercise.
What a fun surprise to find the desks arranged in a new and exciting way every time I come in!
But today really took the cake. There was the computer, of course. The newest and excitingest desk arrangement I have ever seen - stacked in a tower. Whee. The candy wrappers behind the tower. And best of all, the board, covered with Latin scrawling. In green.
I didn't know I worked at Hogwarts. Perhaps you could get the house elves to clean up your endearing little messes ex post facto?
