The letter will read:
Dear <NAME>,
HO, HO, HO! I'm making my list and checking it twice!
It’s almost time for me to make the long journey to you in <CITY>. I am getting ready for a busy Christmas and had just a minute to peek at my nice list and I am pleased to see your name! That's wonderful! This shows me that you are working hard and have playing nice with <FRIEND OR PET>.
As for me and Mrs. Claus, well, we are so busy here at the North Pole. Mrs. Claus is busy with her holiday baking and making sure I get plenty of rest for my trip to you. The Elves are working around the clock getting presents made and organized for the sleigh. The reindeer are eating a lot of vegetables and hay to get stronger for their long flight.
I have a special request before I come on Christmas Eve: Keep up the good work. Remember; you better not pout, be polite, respectful and always behave.
Don’t forget, I'm watching!
I hope you enjoy the holiday season, and you get to enjoy <TRADITION OR TREAT>. If you leave me a snack on Christmas Eve, I like cookies and my Reindeers really like carrots.
Do not forget to go to bed early on Christmas Eve!
Merry Christmas,
Santa
P.S. Remember <FRIEND OR PET> loves spending time with you! Be sure to spend time playing <ACTIVITY> with them! The elves love playing hide-and-seek!
