Dear Santa,
This year I was a very good girl/boy , I get good notes at school and I make my parents to be happy , so I hope you will give me some gift and sweets!
I always want a teddy bear/a red toy car . At 24 december I will wait you to come at my house and put my gift under the Christmas tree. Don't forget my sweets!
I promise I will be a good child and I will not disappoint my parents .
With love, ...... (your name)
