As I'm sure many of your families do, our family has a 
tradition of reading a special "Story A Day Until Christmas".  There are
 numerous versions of this, but I wanted to send Bryan one that would 
work for missionaries.  I know there are rules about what reading 
materials they are allowed, so I spent some time combing through past 
Christmas Ensign issues and gathering Christmas stories that would 
work.  I know they are allowed to read the Ensign, so these should be 
perfect!  I printed one for our family too, and plan to tell Bryan that 
we will be reading the same story as him each night.  Hopefully that will help him to feel more connected and less homesick during the holidays.  I'm putting each 
story inside an envelope numbered with the day - one for each day in 
December leading up to Christmas, and will include all of them in his 
Christmas package.
My kids like to tease me because each 
year when I read our current "Story A Day Until Christmas", I can't get 
through even one without crying.  When I was deciding on which stories 
to include in this version, that was how I decided.  If I read the story
 and it touched my heart to the point where I cried, I included it. :P
 
Anyhow, I thought you guys might enjoy this too, and maybe your missionaries or your family would want a copy.  Here is the link to download it.  Merry Christmas!
