Dr. Jekle and Mr. Hyde

I'm surprised by Zoe's (and any 3 year old's) ability to switch from angel to devil in a split second. For example.. this morning I was giving Finn a broken gram cracker from the remainder of one sack, Zoe wanted one.. I tried to give her the one that I was giving Finn, and she said, "No, its broken"... and took over in a crying fit, slamming the door.. not giving me anytime to offer her the unbroken ones. She came back minutes later, I was still analyzing what happened, and she was acting like it never happened.
