If my daughters love pink and princesses (which may be genetic at this point!), okay. I'm good with that. But good princesses are polite. It's the step-sisters who are snots. Cinderella remains a lady despite her treatment by the stepsisters. Princesses have responsibility. They have to set a good example. They have to take care of their people.
There are also examples in real princesses. Princess Kate, who's technically only a duchess, is one of The Hundred Most Influential People in the World according to Time Magazine. She supports many charities and is to volunteer with the Scout Association in North Wales. She always appears ladylike and professional in public. She doesn't dress like a tramp. She doesn't act like Paris Hilton or Snooki. She acts like a princess and is a great role model! Why wouldn't I want my daughters to act like a princess?
