Well, it's a fake. The parents put the presents and candy in their childerens shoes.
And the presents given on 5 decembre are bought by the parents too.
So someone else put the candy in your shoe. Candy in your shoe is better than a scropion.
And it's mostyl an European tradition. But the Netherlands and Belgium (the Dutch part, not the France part) are the two countries that celebrate it the most. I doubt that anyone in the USA would celebrate this.
