I was about to get a little defensive until I realized I was thinking of a different song. I was thinking of One Last Christmas by Matthew West. It's a somewhat sad but touching song about a family with a terminally ill boy who know he won't make it to the end of the year so they start celebrating Christmas (with the help of the neighbors) in September. Eventually the whole town gets in on it and he has a smile on his face to the last moment.
What makes the song even more poignant is that it's based off a TRUE story.
