I have the sweetest nieces. The older one is turning four this weekend. We were playing the other day at "store"... I was supposed to ask if she had something in the store and she would run and get it and charge me for it. So I ask her if she has milk. She goes - sure... but it's a bit torn... and it's only for cows.
(Ya see... there was a picture of a cow on the carton... hee hee...) I love kids' logic. It's so oddly accurate yet so off.
