My family has always celebrated Christmas. Never got too much into it (I was never told that Santa Clause was real...and I never believed it either!). 
I must say, though, that I've never felt so un-Christmassy before in my life! 
  
And it came from the Catholics, who took it from the equinox celebration and also implements from the Roman holiday of Saturnalia - a worship of their god Saturn. They decorated with holly branches, gave gifts, and had big feasts. Sound familiar??? 
Of course, those celebrating the equinox (I'm not sure which culture it was) weren't better. Believe it or not, but it went something like where they thought that some big monster was eating the daylight, and a few days after the equinox when they realized the days were getting longer, they'd celebrate because their god had forced the monster to puke up the daylight or something like that. Funny that they didn't realize that this happened regularly... 
  
I'll stop my ramblings. Theres a small bit of Christmas history for you people!
