Christmas Eve is all about the anticipation. Everything about Christmas Eve is in preparation for the big day; a dry run.
You eat, well you eat because the body needs fuel to open gifts.
You dress up, but not quite in your Christmas best.
You open a few presents bought by relatives.
You leave food out for the reindeer.
You leave out cookies and milk and say your final prayer that he will come.
You don't even realize it was never an option; he was coming all along.
Merry Christmas Eve!
