Dude I can daydream about pizza all day long. It doesn't matter how recently I was eating pizza. I can even be in the middle of a delicious slice of pizza and still daydream about other pizzas, or even how great the first bite of that particular pizza was. Pizza is the food of the gods and that is that.
