I was listening to the radio on the way home from my office the other day and heard the story of Dax Locke, a 13 month-old child diagnosed with terminal Leukemia. Since it was unlikely he'd make it to Christmas (it was in early autumn), his family started putting up the tree and the lights. Then the neighbors followed suit, and then the whole town.
For obvious reasons, it stuck with me. So, I tracked it down and found this YouTube video by Matthew West. Caution - it will most likely bring tears to your eyes, so be warned.
And if you're looking for a place to contribute to, this would be a good one. So open your checkbooks and spread a little cheer.
