Dear Santa Claus,
Merry Christmas! Can you get me a [present you desire] on this Christmas? I wanted this from a long time and I think getting it on Christmas would be great. My dad told me to write you a letter and tell you how glad you would be to get a [present you desire] this Christmas. I think I’ve been behaving very well this year, because no one got annoyed at me or made me go to my room since [last year]. And getting a [present you desire] from you would be a great reward for having been such a good kid. I hope you will get me this Christmas. Thanks, Santa. and Merry Xmas again!
