Being the princess of an entire kingdom can be pretty fun.
Unless your two aunts also happen to be rulers. And have power and authority which supersedes your own. That can be a pain. After all, what good is being princess if you can't enjoy it once-in-a-while?
Celestia knows Cadance is right for the job, or she wouldn't have seen fit to appoint her niece to the position of Princess of the Crystal Empire in the first place. Sun-butt needs to quit agonizing over every last detail and just relax.

Then again, maybe there is such a thing as too much fun. Hopefully Cadance and Luna's prank won't go too far... Like destroying the kingdom or anything. Oops.
