It is easy to loose sight of the meaning of Christmas, during the Christmas season.
It's sad, but we tend to get carried away with all of the parties, reunions, traveling, buying and baking that we forget Christmas is Jesus' birthday.
This year during your Christmas party, try focusing it on Jesus (assuming you are in a setting that you are able to talk about Jesus). Buy him some cupcakes, get some balloons, sing happy birthday... Celebrate Jesus on his birthday.
You will be suprised at how much more smooth your Christmas party goes when you change the focus to Jesus.
