Christmas Eve is actually our family day to celebrate. Every year on December 23rd, our family gets together and opens a gift which is always pajamas.
Our kids get together on their own and my wife and I wrap gifts well into the night and watch movies or shows we need to catch up on.
This frees us up for Christmas Day to travell to other families homes for the celebrations. It's a good system that has worked for almost 30 years now.
