Many people write a Father Christmas letter addressed to Santa when making wishes for the Christmas season, either for gifts or generally prayers. It is symbolic for expressing desires and aspiration on paper or making what you want known. Here is a sample Father Christmas letter.
I would like a skateboard and a merry go round for Christmas. I want to be a professional skate boarder and win many trophies. We will be rich and my mom will not get to work after many hours. My brother, Mathew would like a game boy to replace the one he lost while on a safari to Africa.
Mom told us that you receive so many letters but I know you will look for ours and get me the presents. Thank you for the last Christmas presents. I gave the trousers to my brother after I outgrew them.
James and Mathew
