So at this point I'm intrigued and I ask "Whatcha doing" which is a line she loves from some show on the Disney Channel or Nick (I think it's called Phineas and Pherb if I remember right) adn she says she's "Measuring things" which she really loves to do - mini measuring tapes are a favorite toy of hers!!!
And I watch a little closer and sure enough she is measuring things, I'm just not sure what these things are because I think she's imagining them. You can see where she has the one side all straight and the mess on the side is where she's already used it to measure stuff.
Priceless fun (well really cheap fun) that kept Riley entertained for like 30 minutes - oh I love the sneak peaks we get into how are kids brains work!
