White Christmas - Love snow for Christmas!
Turkey Dinner - Hands down, although we do normally have both for Christmas Dinners for our extended family is decent sized.
Opening gifts on Christmas - I love Christmas morning with the kids, but have always had Christmas with my parents on Christmas Eve which is fun as well.
Sugar Cookies - Love em
Real Tree - Love the real trees even though they are messy and take some work, but love the smell.
Giving Gifts - Doesn't get any better than seeing someone open a gift with something they really wanted or need.
Small Intimate Christmas gatherings - I love the family parties personally. We always get together with friends as well a couple of times over the holidays for football watch parties or white elephant gift exchanges, so that a great time too.

Bottom line is I love Christmas and always have.

Totally agree with Vlady on the Prime Rib!
