The world isn't only black and white

Last week Luke and I went to the grocery store to pick up one thing: cheese.  Luke, however, had his mind set on a cookie from the bakery. So while he waited at the bakery counter for someone to notice his cute self, I ran across and got the cheese.  When I got back to Luke he was silently chewing on a cookie.  He took two steps to follow me to the till, stopped, smiled and said, "The world isn't only black and white!"
I laughed until I cried.

Just so you know, Luke is deep, but not really on that level yet.  We have a book about a penguin named Edna who is looking for something that's not black, white or blue.  When she discovers some scientists out on the ice in their orange tents she says, "Wow, the world isn't only black white and blue!"  Luke loves to regurgitate his favorite stories.  And I love to hear it.  Especially - especially out of context.
