We have taken most of them down, but one string around the living room has been up since we had our first christmas here. We decided that it made a nice soft light when we didnt want the main ones on.
The tree is still up and will probably remain so until the end of the month. I hate this frigging time of the year. Everything is gray, dead, colorless to the eye and frozen to the touch. A lighted Christmas tree on the weekends reminds one of all the good, warm and pleasant times not long passed.
