We have a couple traditions for Christmas Eve. 1. We open one present on Christmas eve. 2. Instead of buying little presents for each sibling, we draw a name, and buy one sibling a nicer present. So, on Christmas eve we open the present that we get from our secret santa.
My parents opened a couple of candy filled ornaments, and then my dad decided to use it as jewelry. Cute, I know.
Here in Ecuador, Christmas Eve is the big event. People stay up past midnight to open presents, eat good food, and enjoy family.
