In August 2004, my 3 1/2 year old niece Hanna died of cancer (http://www.caringbridge.org/ms/hanna/). In November of that year on what would have been her fourth birthday, her friend Eli was with his family at DisneyWorld. He had the Disney Princesses sign a balloon with messages for Hanna and they released it in front of Cinderella's Castle. Eli's little brother was a patient with Hanna at St. Jude's Children's Research Hospital. You can see the photos from his balloon release at http://www.bens-story.com/disney.html.
