An Post helping to sort 130,000 replies from Santa Claus
Little Mark, who lives in Meath, admits that he has not been very good this year in his letter to Santa.
"For Christmas this year, I am asking for a desktop computer. Even though I have not been very good this year, I hope that you can still see it in your heart to forgive me and to give me what I am asking for. I love you Santa," says a repentant Mark.
It's one of the tens of thousands of letters that have passed through the GPO in O'Connell Street en route to the North Pole this year.
Some kids are very thoughtful, asking that the sick children in hospital are being cared for. This year, one child even mentioned the victims of the Paris attacks.
From the cute to the complaints, it's all there in the sack-loads of mail that Santa has received.
"Sometimes you give me what I don't want, but it's ok," said one gracious youngster in Co Tipperary.
But, while some kids have reames of lists - one year a child sent a list that ran for 10 foolscap pages - some children don't ask for anything.
The mountain of correspondence is a big workload for the staff of An Post. Santa replies to between 120,000 and 130,000 letters every year in a free service provided by the company - according to Eimear Breen, a communications executive with the company.
An Post does appreciate a stamp on a letter to Santa, and there is no charge for a reply, but unfortunately not everyone supplies an address.
"We have a special arrangement with Santa in the North Pole - we deliver his responses to the children," she said.
"It is a company tradition and we love it."
Staff are doing their utmost to deliver the responses from the big man on time.
