I spent weeks trying to convince her to be Eowyn. I told her the story of how Eowyn slew the King Ringwraith. I showed her pictures online of her pretty dresses and pretty hair. I told her she could use her shield and sword. We practiced saying "I am no man!" She seemed to enjoy it all, but every time I asked her if she wanted to be Eowyn for Halloween she said, "No, I think I want to be a pink ninja."
So, I gave up the idea of Eowyn (for this year) and bought her a pink ninja outfit. Z was already planning to be a ninja, which I'm pretty sure was the major influence on Eden's choice. But, when all was said and done, they did make a pretty good pair of ninjas.
