Santa loved his job. But sometimes it just was too much and he started to think to quit.
Consider that he had not a choice at all. Santa's job was passed through generations and generations. He was given the job when he turned 18 and he just dived into it.
At first he was thrilled, all the fun was there: flying, knowing what everyone wished for, getting into a chimmney in the middle of the night....
However, after 25 years of doing the same year after year, he got tired. He started thinking of getting a family and spend a quiet Christmas at his home for a change. Rosalie, a dressmaker who did magic with her hands might have something to do with his decision. For half his life , he has thought about others, it was his turn now.
