If you are the lucky tree to get picked, you could experiance a lot of great things. Like when they put you up in their living room, and decorate you with shiney, and colorful ormaments. You have a job of keeping all the presents under the tree as well. One Christmas morning you get to watch the family's faces as they open up their presents.
