(scene opens in a toy strewn finished attic, heaps of dirty intermixed with still folded clean on the floor)

Me: (still has her cool) Okay boys, welcome to Sunday morning, this room needs to be cleaned. (waves her hand to encompass the room) Please pick all this up; clean clothes hung up, dirty laundry in the basket, books on shelves, legos in bin. Okay?
Alpha/Beta: Okay

(insert busy mom montage of washing dishes, feeding Delta breakfast, helping Gamma get dressed, more dish washing, reheating forgotten coffee three times)

Me: (returns to attic, stands in the only perfectly clean space on the floor) Oh my god. Why the hell is this room still a wreck?!
Alpha: You told us to clean this part. (mimics maternal hand wave that perfectly circumscribes the only clean spot on the floor)
Me: (strokes out) Pick up everything on the floor. Every. Thing. On. The. Floor.
