"Hurry Up!"

Is there another definition to "hurry up" that I'm just not privy to??!! Why is it that when you tell your kids to "hurry up" with an obvious urgent, borderline panic in your voice several times, they still just saunter along and stare at you blankly like you're the one with the problem?? Ahhh, the joy of having no concept of time!! Maybe I'm the one with the problem after all! Hmmm...thinking on that one.
