The Fight

I was working with Harry and Draco today. They started to disagree on how much dragon blood to add. I told them that they were both very wrong but was ignored. Anyway, they started to fight and Ms. Hermione Granger, Harry's friend, had to come help me split them up. When will they see how difficult they're being? It is a good thing I like challenges or they would both be hexed by now. Or I may have just forced them to do as I want them to.
sincerely,
Sybilla Snape

PS: I will not be denied what I want, of that I can assure you.
