As quoted from Margaret: "This is the most funnest thing I have done!"
And yes, she is scrubbing the kitchen floor. She has prepared cereal bowls full of water, soap, and rinse water. She has collected several sponges and brushes and towels. And she begged to stay up later so she could clean the floor some more.
The mess she is making is far worse than the clean spots she's creating. But who cares? Really, does it get any better than this?!?!
