Addendum...
Apparently, I need to be more general when I make rules...
Yesterday, I told Dawna to stop drawing on Larry's face. She was very good about sticking to it... But now I'm seeing my mistake...
Today I had to say, "Dawna, you're not supposed to draw on ANYBODY's face!" when I saw a butterfly-faced Dawna and a "Harry Potter"-Xochitl...
Figures...
