It's a partnership that dates back over 100 years... the post office and Santa Claus. For some kids, a true Christmas miracle is delivered.
In an era when you can write on Santa's Facebook wall, and track his Christmas Eve progress on twitter, the old-fashioned method of reaching him through the postal service, still endures.
“Children all over write letters to Santa, and put them in the blue collection boxes, or put them in their mailboxes, and they come to us“ said Sharon Tennison.
Here in Washington, D.C., before letters get to "Santa" they go through Serita Bush.
“Dear Santa, I am 9-years-old, and I live in Washington, D.C. I have been a good girl this year...“
The letters start trickling in over the summer, right through these final days before Christmas, with kids trusting the post office will deliver their most important letter of the year, in time.
“We get the mail out, so without an address being put on it, Santa Claus, I guess the kids just assume where the Post Office knows where it goes,” said Bush.
Bush has helped with Santa’s mail for about 10 years. She calls this year's batch heartwarming, and heartbreaking.
“They're asking for coats and boots and necessities that they're used to having, that they just don't have,” she said.
The postal service's "Operation Santa" matches some of those wish lists with Santa’s most generous little helpers in cities and communities nationwide.
“They come in, they sit down, they select a letter,” said Laurie Chapman.
Even in tough times, keeping the mystery of the post office's North Pole delivery alive for yet another year.
“You wake up on Christmas morning and you thought, "Yes!" he must've because that item I asked for is there,“ said Tennison.
