Hmm...
It seems to me that not many students have been practicing wandless magic techniques as I have asked. I have assigned multiple essays and readings that should have been helpful. I suppose that some students believe they have more important priorities rather than doing their homework, let alone practicing certain counter curses? This is very dismal. I suppose I will have to hand out more detentions. I'm sure that will make Filch delighted. Same goes for his stupid cat.
