Max and Maya have been spending A LOT of time pretending to be Diego and Alicia from the Go Diego Go!  series.
Max, running into the room,"Rescue Mom, me and Alicia need batteries!"
Pulling out the pretend batteries from behind my back, "Here you go."
"No Mom, we need real batteries!"
"Well, if you can pretend to be Diego and Alicia then you can pretend to have batteries"
Amazed look on his face, "OK!"grabbing the pretend batteries from my hand.

Score one for mom, I beat kid logic with their very own logic.
