It's a little lonely, but at the same time very warm and sweet. Is he trying to tell us you've to make it a merry little Christmas for youself, (even) when no one else is going to make it a day of happiness? Or is he telling that Christmas makes all troubles far away and warm our hearts, even in times that aren't warm at all?
