I'm Christian, and Christmas was held pretty highly when I was a kid. My father's side would come together at my grandparents' house, and there'd be gifts for the kids and my grandparents and a huge feast. It was a wonderful time, but since my grandparents have passed, the "reunion" has ceased. It's a bit depressing. We hold a Christmas Eve party just between my parents, brother, uncle, aunt, and their children since they live just down the road from us. Also, in the middle of December my mother's side comes to visit. They live only an hour or so away, but we really only get to see them once a year, because they don't like "traveling".
We don't have much money at all (especially this season), so it's a little depressing that I can't do a lot of the "fun" Christmas things like baking treats for people, buying gifts for people, or going out and doing stuff.
I also don't like how close Christmas is to my birthday, so there's always the stress of "what have I done this year" hanging over me.
I do enjoy Christmas music. Since I'm more into classical singers, it's really the only time they play some of my favorite singers on the radio. Then, again, I'm not always in the mood for it, especially when I'm feeling depressed.
I like the decorations, cold weather, and snow too.
I really hope this doesn't offend anybody, but:
The thing that bothers me the most (more than the commercialism) is the fact that most people put on their Christianity like it's a winter sweater they've kept in the dresser drawer all year long. They wear it this time of year, and then it goes back in the "drawer" until next year.
