Dear Professor Dumbledore.
This is a outrage! I demand immediate action to fix the situation! The entire evening was thoroughly devoid of any Halloween cheer at all because of this fiasco of a Halloween celebration! How could you allow Professor Lockhart to Cheat in such a blatant display of favoritism? Not that there is anything at all wrong with Professors Sprout and Vector, and Madame Pomfrey, but it is a well know fact that they Favor Lockhart over myself and it was obvious that I had the better costume and yet they still both voted for Him! I mean I had a completely authentic Quiditch beaters robe from the Holey Head Harpies! Handed down to me by my grandfather! And Lockhart came dressed as himself!
This is all rather upsetting as I am sure you can imagine. And I would have hoped that you had picked staff members that could remain unbiased in the face of a costume contest. I am afraid that I will be forced to put this down in my Official Report.
Also, Please make it a priority to track down whoever it was that did that most horrid thing to Mister Filche's cat.
Hoping you, at least, had a pleasant holiday.
