"I really feel sorry for her parents and her. I wish I could help. I always wear a yellow ribbon pinned on my shirt and yellow ribbon in my hair. Most of the time I wear yellow clothes too.

I think it is disgusting how someone can take a child away from their parents. Yes there is a downside to it for the parents and that is Maddie and her sibling shouldn't be left alone no matter what, but no one deserves to be taken away! There are some sick people in this world and they need help but please bring Maddie home. Make her come home alive and well, no young child deserves this as they have their whole life to experience... BRING MADDIE HOME!!!"
