The image of the jolly fat man in the big red suit is something that every child can conjure up immediately. Santa is one of the first people we learn to recognize that isn't "mommy" or "daddy".
But what about kids who can't see? They can be told about Santa, but he's little more than an idea.
Little Matthew Wolf is six years old and, like many kids his age, he loves Santa. Matthew is also blind and autistic.
His mother, Misty Wolf, recently shared a Facebook post of Matthew's visit to a mall Santa, and it seems like she encountered the real St. Nick.
"Best Santa ever," she begins her post, which has now gone full viral with millions of people having seen it. "I whispered to Santa 'He is blind and autisitic and is very interested in Santa,' He said 'Say no more.'"
Santa got off his chair and knelt down in front of Matthew. He gently took his hands and put them on his face.
"He talked to matthew for a long time. Let him feel all over him. Told him to pull his beard, feel his hat and talked about his red suit. He asked Matthew if he wanted to feel anything and Matthew said 'your eyes that twinkle' (from the poem 'Twas The Night Before Christmas) so Santa let him touch all over his eyes for as long as Matthew wanted."
It was the first time that Matthew ever got to really experience Santa. For everyone else, the interaction filled their hearts with joy.
"I believe!" Arlene Newman exclaimed on Facebook.
"Amen. Santa loves everyone," said another commenter.
The post has almost 100,000 shares, and many more comments and likes. It's spread around the world as people rejoice in the pure moment.
It went well beyond the standard photo on Santa's knee, as Matthew even got to fully interact with the display.
"Then Santa said have you ever felt a real reindeer (and) carried him over to the display area. Matthew pet the taxidermy reindeer they had set up."
"My heart was full seeing Matthew so interested."
If not a real Christmas Miracle, this Santa came close to magic with how he helped a little boy grow his world and in the process made us all believe in Santa again.
