what is the true meaning of Christmas?

Last night I watched "A Charlie Brown Chritmas" for the umpteenth time, and I always side with good ol' Charlie Brown when he asks what is the true meaning of Christmas. It is Linus, who, upon seeing the scrawny tree that Charlie Brown has brought in, the one that everyone laughed at, gathered his friends together and gave his oration. That oration always gives me goosebumps...because it is so simple, really! The true meaning of Christmas is exactly what it is: it's about the birth of a Savior. It is not about how much money you spend or how many presnts that you get. It's all about the birth of a Savior who came to us, to show us what God's love was all about.

Why do we complicate things so?
