Me: "Do you like ice-cream?"
Princess: "Do you have to ask?"
Me: "Do you like this ice-cream?"
Princess: "This taste good." (Note: she had gummy bears and white chocolate bites mixed into it.)
Me: "Do you know how much this cup of ice-cream cost?" (Note: she has no concept of money.)
Princess: "Erm ... Anyway, Daddy is the one paying. You should ask him."
