Beware of the silence

This afternoon, I was sitting in the living room ordering a canvas print of this:

and thinking about what a sweet little girl I have.  Then I realized it was naptime (score!).  I went to her room, where she was playing quietly, and found this:

Then I went back to her room to get the cup and noticed this:
