Too Quiet

I was in the kitchen busily cooking fundraiser casseroles thinking, "Wow, Thomas & Ruthie are playing very well and really quietly.  This is great!  I'm getting a lot done."  I should have known better...

Who could possibly be the culprit?

She's so ashamed...

...yeah, right!

 All is well -- let's just say I'm very thankful for washable marker and magic erasers.
