Christmas eve, actually. Especially if it's snowing, we all go over to my grandmas in the evening and open presents. There's tons of paper everywhere and it's a lot of fun.
Mine is actually Christmas Eve also. I think it's fun waiting for presents from 'Santa' and being with family. Also it snows almost ever Christmas Eve down here (oddly) and it's so magical.
Nothing compares to christmas, in my honest opinion!
No other time of year when I see all my family and in general, you can actually enjoy life without people thinking your slightly crazy.
It's a toss up between Thanksgiving and Christmas. I love thanksgiving because its the transition from the fall to the holiday season, and thats when they start putting christmas music on the radio, ect. I love christmas in the fact that its such a fun day, and its fun to see my little sisters faces light up when they open their stocking, ect.
