I reason I want always wanted to be a princess was because you don't have to worry about the red tape of international law and politics like a commoner when you are championing a cause you particularly love. Sure, everyone is under the United Nation law, but you are not subject to worrying about your finances, travel accommodations and arrangements because all that is done for you. There is a freedom to roam and do what need be without the hoops to jump if you were not a princess and aside from all the altruism, I particularly like the idea of being a princess too :) Some of it is that I don't have to make particular decisions on what I need to become or achieve in the future, but your life is pretty much from the get go at the height of where you are suppose to be. You are not working to climb some invisible ladder of success, but merely need to fulfill your duties as a princess and championing a cause is part of those duties.
So you see, I'm not as prissy and as girlie as you think I was when I first told you I wanted to be a princess. Just maybe a little less so?
