What is the Christmas spirit?

The Christmas Spirit

If you ask 10 people what the Christmas spirit is, you'll probably get 7 to 8 different answers. Going beyond those different answers, there is something, the Christmas spirit, that makes people more selfless, more friendly, more kind, and generally much nicer people at Christmas. Unfortunately, due to commercialism and other factors, it seems like the transformation the Christmas spirit brought about in years passed has lessened more and more.
