Most of the parents tell their kids the biggest lie ever: Santa Claus does not exist.

Santa Claus does exist. However, as stated in this brilliant answer, his requirement to put you on "Good" list were bit too high. And also, to be put on "Naughty" list, you had to be worse than all serial killers combined.

As a result, Santa did not deliver a single present in past 100 years. He did not even go to journey during the night of Christmas in past 100 years.

We started to believe Santa really does not exist. And at some point, we started to tell this even to our kids.

However, this year, Santa decided to rework his metrics of "Good" list. (And he is going to rework only "Good" list metrics, his "Naughty" metrics stay untouched).

His reworked metrics put almost every single kid (95%) on "Good" list. He also managed to secretly copy all the letters addressed to him, so he knows what the kids wish for.

On December 25th, 2015, in the morning, loads of families will discover "extra" presents under the tree. These presents are going to be addressed to the kid wishing for them and containing exactly what the kid wished for.

How does society react?

To sum it up:

• 95% of all letters addressed to Santa, or to his mythical equivalents (Father Christmas, Weihnachtsmann, ...) are fullfilled
• Santa Claus is mythical creature, he wents un-tracked and un-spotted during the night of gift delivery
• Should there be camera or any device able to spot the "intruder" in given home that device will malfunction for time of gift delivery. Then it will continue to work normally
• Presents are "A class" presents "Made in North Pole". Santa's elves create perfect copy of branded products. So if you wish for PlayStation 4, you will get PlayStation 4, but made by elves (and compatible with PS4 by Sony)
