To make a long story short, La Befana is like Santa, only she's a witch and she gives candy, not presents (specifically Kinder brand chocolate, if my local grocery store has anything to say about it). And she comes on Epiphany Eve, not Christmas Eve.
And as you may have guessed I'm bringing this up because today is Epiphany. (I'm not sure how to wish you a good one - Merry Epiphany? Happy Epiphany? ) ! I'll save that explanation for tomorrow though.
