If I was an Elf I would help by feeding the reindeer. I would make sure they are ready and awake and give them a test run to make sure they are ready to go.I would always make sure to give them food. So they won’t starve during the trip.They always need a test run. So you can make sure they are fine for the trip. Finally you need to make sure they are awake and ready to go. As you can see taking care of reindeer is a lot of work!
