Happy St Nicholas Day
This side of the world you do need to clean your shoes the night before.
And get presents in the morning of 6th of December.
Also from the wiki page:
"In Hungary, Croatia and Romania, children typically leave their boots on the windowsill on the evening of 5 December. By next morning Nikolaus (Szent Miklós traditionally but more commonly known as Mikulás in Hungary or Moş Nicolae (Sfântul Nicolae) in Romania) leaves candy and gifts if they have been good, or a rod (Hungarian: virgács, Romanian: nuieluşǎ) if they have been bad (most children end up getting small gifts, but also a small rod). In Hungary he is often accompanied by the Krampusz, the frightening helper who is out to take away the bad ones. "
I don't remember this "take away the bad ones", but I can imagine they do say this.
