I'd be the atheist in your foxhole, anytime
*The practical charms to clean a kitchen are simple enough, but Sirius has only mastered them recently. He is Not Allowed To Cook Ever Again as of a few months previous, after creating the most searingly spicy curry possible without using actual fire crab. Over noodles from the place up the street, Remus and Sirius had then struck a deal: for the safety of the world at large, Sirius would stay out of the kitchen, and instead take over cleanup duty after Remus cooked.
For this reason, Sirius is currently spinning plates through soapy water with his wand as the drinking glasses polish themselves dry in midair. He has not perfected the choreography of this particular bit of charms work; plates are dancing in the sink a bit more vigorously than is really wise, and the glasses seem to only be getting dry on one side. His tongue is poking out from between his lips and he is squinting into the sink as if it has challenged him personally. When the doorbell rings, his surprise sends all four of the plates in the sink leaping into the air. One collides disastrously with a half-dry tumbler, showering his feet in shards of porcelain and glass. He bites back a series of curses, and then shouts over his shoulder:*
Remus, tell them we don't want any!
