I can do this year round - I simply love Christmas! For us (for my family present and past) it has always been about cheer, decorating, lights, tree, friends, fireplace, eggnog, carols, cards, and the list can go on and on.
If I wouldn't know for sure it's going to become a bore (do you remember Donald Duck's three nephews? when they wished every day was Christmas and they got their wish?) I would sing carols every day. But I realize it's special because it's just once a year - so for us is about 40 days, from the beginning of the fast to a few days after Christmas: the house is getting dressed (in a continuous move, it really happens over a few weeks, until we are done by decorating the tree), brighten up with lights, there is cooking and baking happening, there is card making, caroling (both by the radio and ourselves), special concerts, and then the house is full between Christmas and New Year with family and friends.
Below is a wonderful clip - from the perfect cooperation these 4 gentlemen show, to the beautiful music, to the actual video-recording (I really like that train idea! I think this year I'll bring the toy train nobody played with in years just for that :) )
Enjoy! (and bear with me - it won't be all Christmas carols until Christmas, I'll take breaks here and there :) )
