HAAAAA, having Snape parrot his words back to him that way, I could just hear it...and THEN, I had this flash from the movie 'Fried Green Tomatoes'--have you seen it? Where Cicely Tyson says in a singsong voice, "Secret's in the sauce." If you haven't seen it, just totally disregard that--I think I'm tripping on Diet Pepsi or summat.
Anyway--great drabble! I do have to mention that it's Alohomora. I'm done now.
