You walk around this house demanding sushi on a regular basis. Sometimes it's the first thing out of your mouth when you wake up in the morning. "Shushi!" My insistence that we don't have any sushi and that I can't make it appear out of thin air does nothing to quell your demands or extinguish your enthusiasm. "Shushi!" is a daily chorus around here, and it gives us the giggles every time.
So now you know what a cookie is. The questions is, what were you asking for in the first place? Perhaps we'll never know.
