A few things: my kids wrote a letter to Santa, ostensibly telling him how good they were that year, but they usually ended up talking about the reindeer. I have kept all the letters. Santa wrote a reply on the back.
I also like to lie under the Christmas tree and watch the shadows of the blinking lights on the ceiling.
After the children were in bed, Mr. and Mrs. Claus liked to make love before the fireplace. That is, if they weren't required to put out the fire so Santa could get in.
One more ritual is the sojourn to find the perfect Christmas tree either on our property or in the nearby Forest Service land. You have to have a permit, but it is easy to get.
