Dearest Moldyshorts,
I believe I know why the Elder Wand blew up on you. You said "ABADAKADABRA!" instead of "AVADA KEDAVRA!"
While both are similar, "ABADAKADABRA" is very closely related to the muggle saying "Abra Cadabra" and, while created for sheer nonsensical amusement for the more IGNORANT of the illiterate thugs who can't tell a good book from twilight (Doesn't deserve capitalization), can easily be destructive if pronounced incorrectly, with power being pushed into it... Hope this gets to you!
Enjoy!
Hannah
PS. Ravenclaw house too! I channel my inner Luna... Need I say more?
Dear Hannah
Silly Muggle... I have spoken the same curse over and over again as years passed. It's even known as my signature move! How can I not pronounce it right? So your argument is invalid. Try again.
