I'm actually quite the bah-humbug-y scrooge, but I guess I would have to say Christmas. I really enjoy Christmas day since we moved out here to Missouri. It used to be fairly hectic in NC, running from one house to the other as we worked in visiting everyone. Now, we just get up and have a leisurely day at home.
The kids always get up way too early, of course, but we let them play with anything in their stockings and any gifts that are left out unwrapped. That usually tides them over until Josh and I are ready to wake up. I've already given Josh his main present (a rather expensive pair of fjallraven pants), but I've got him a thing or two that he can unwrap on Christmas. Hopefully the kids will be happy with their gifts. I'm mainly looking forward to spending quality time together. And hopefully having some kind of awesome feast, although I haven't planned that far ahead yet.
