"Zone of Inconvenience," repeats Sam as an inconvenient panicking passerby knocks her spellbook to the floor, where it inconveniently ends up face-down in the mud. "At least it affects Remus, too." Shi wipes off the spellbook, inconveniently dirtying the sleeves of hir best robe, and casts the next spell: Divine Spell of Bad Hair, which promptly messes up hir previously-smooth and silky hair. Shi sighs at the sheer inconvenience of the situation, and waits for hir book to reset, which is just inconvenient by itself.
