Spilled Milk

We usually don't allow open glasses of milk in the living room, but this morning I was sitting in the floor with Laura sharing some milk. Well, I needed to get some reading done before class so I got up and sat on the couch with my book and told Laura she could finish the milk. Well a few minutes later she inevitable spills the milk...she tells me about it by saying, "Mommy, you're not supposed to leave milk on the floor".
