This is a basic "I've been good" letter to Santa from a kid looking for Christmas goodies.
I am writing because I wanted you to know that I have been very good. I have gotten along with everyone this year, and not even hit my <person you haven't hit> once. I would appreciate it if you would bring me a <toy you want> on Christmas, because I have worked hard to earn it. Thank you very much. I hope Mrs. Claus and the elves are fine.
