Sit down here and let me have a look at you. Disgraceful, really ...
You need to send me an owl Madame Pomfrey with what you have been cursed with.
I have plenty of tonics, but they are very specific with what they cure.
Tell me the correct countercurse and I will be able to relieve you from your symptoms.
Once you have done so I will put a sticker below letting the whole school know
how wonderfully clever you are. You will be proud of yourself. But until then, enjoy being cursed.
