Are your parents gone already for the 4th holiday? If so, there's no way you can wait until they get back! Take it to a camera store and explain what happened and everything and it's possible they can just "snap" things back into place. And if you play the "poor innocent little girl whose mommy and daddy are out of town and you're just lost without your camera" routine, they might just do it for free if it's nothing extensive. Otherwise I don't know what you're going to do until they get back. I know how you love your camera. So have you ever counted exactly how many pics you have on your computer already?

Good luck!
