Avoiding the inevitable

The little girls and I are having an ongoing battle of wills. I want their room kept reasonably clean for a 6 and 8 year old. They want to play in it the minute it is clean, trash it, and then use every other room in the house to play their games, and set up house.

So I sent them up to their room, to clean it up after dinner (around 6:30) and it got VERY quiet. I went upstairs expecting them to be quietly playing and avoiding cleaning, and instead found this:

Notice the bright sun outside.... hours before bed time. This is their latest tactic. I intentionally didn't include their floor in the picture- it's too embarrassing.
