Being married to a Prince in real life is like a fairy tale that came through for some people. However, the royal life in the real world is nothing like what they speak about in the story books. Being a Princess is more difficult than most people think. The only similarity between a Princess story and the Princess in real life, is that both of them met and married their prince charming.
This is amazing, but in the real world, that is not all there is to being an important member of the royal family.
