He's over 200 years old?!?!?!

Trying to explain something like "Santa Claus" to kids is tricky.  "He looks like Santa Claus, but his name is St. Nicholas.  And he comes to your door on the eve of Dec. 5th, and if you put your shoe/boot out then he'll fill it with goodies- IF you've been good all year."  
Gracie:  "Oh, I get- he's a cousin to Santa!"
Me: "Well, no... St. Nicholas is more religious than Santa Claus."
Jada: "What does religious mean?"
Me: "Uh....."
Gracie: "You mean he's over 200 years old?!?!?"

Why is this so hard!

Well, hard as it was, St. Nicholas visited our house so that when the kids woke up on Dec. 6th there were treats in their boots.
German treats!

    The boots were all lined up like this,

 But St. Nicholas must have known better than to keep them there.  So, when we woke up, the boots were put up.  Can you see who would/could have been a culprit to some Christmas candy?

 Thank you St. Nicholas!  The kids are still calling you Santa Claus, sorry!
