not necessarily because it's the logical curriculum.

plus, as someone else has pointed out (actually, maybe it was you :}) it's not like there really is a logical curriculum for DADA, what with a different teacher almost every year, each one with different ideas... i mean, until someone actually does decide to prepare them for war (DA anyone?) ...who's to say that the evil boggarts aren't out to get them.

...ok, and now i'm actually thinking seriously about that, what with molly's fit in OotP... sigh... damn these books. can't make a joke but it's serious, can't kill someone off (ohgodsbadpun) but it's funny... >:D
