Is Christmas a unilaterally happy time for you or is it stressful?

What percentage is happy and what percentage is stressful (totalling to 100 %)? What parts of the holiday do you find stressful?

I find gift buying somewhat stressful and trying to ship my gifts to get them to their destinations by Christmas very stressful.

Then, on Christmas itself, I really miss being with my family. I used to worry about what would happen after breakfast and present opening (should we go to a movie or go out to eat?), but now I just enjoy the peace, quiet and music, as well as the company of my husband.
