Well, I'm sure the point is to get to the small but expensive gift in the center. There is something in there for her, right? My mom did that with me once, and I think it was a gift certificate for something I really liked at the time.
I got one of those once. At the end, there was a card, saying "Did you find it? It's taped to one of the boxes!" I sat there tearing through all the boxes again and again looking for what "it" was. Turned out to be an autographed guitar pick.
