In my close work with DADA Professor Lufkin, he has expressed concern that students at Hogwarts are not proficient when it comes to conjuring their Patronuses. He can get very frustrated and irate when his lessons aren't taken seriously, when students do not understand the importance of DADA..and he is a wee bit frightening when he's upset!
I think if we all post our Patronuses to our blogs as soon as possible, we can avoid an unhappy professor (and make my job easier! Taming the wild beast can be very exhausting.) Let's show him just how talented we at Hogwarts truly are! Madam Headmistress, dear Professor Lufkin would even like you to conjure your Patronus and prove to him that you are worthy of your lofty position. I know, I know...he's sometimes harsh and unyielding, but I can handle it.
