silence is golden

Or is it?
We've all had one of those moments when we think, "Those kids are sure quiet, what in the world have they done now?"
That was me tonight.
I actually caught up on some emails while they jumped in the bath. I could hear them softly talking and giggling but then I realized something was up. Up, down & all around.
This is certainly not their first attempt at redecorating their decrepit bathroom but I'm pretty sure it's the first time I've shared it here. And this time was quite the masterpiece. Perfectly timed, of course, because the tub was just scoured yesterday. How DO they know these things?
