I was thinking of this:

The siblings decide to hold another bet. This time, they challenge each other to sleep in a different bedroom than their own. However, the siblings begin to like the room they chose, and decide to stay there. However, as time goes on, the siblings wish to move back into their own rooms since they miss being there.
