busted.

I should have known that something was up, when I asked Sadie what she was doing hiding behind the sofa, and she replied,"coloring!" but in her I'm-doing-something-I shouldn't-be voice.  At least she didn't take the pen to the couch. (although there is green crayon all over the back.)

Luckily soap and a Mr. Clean eraser took it off in a jiffy. Locking up my pens now...
