I read this article on a family, the Morgans, who refused to take down their lights at first because Mrs. Morgan loved them, and then out of spite for someone who complained BETWEEN Christmas and New Year's. While I think Mrs. Morgan has the right to keep them up all year because she loves them and the family is paying their bills and taxes, I don't think doing it for spite is the right reason.
But it sure is kind of funny.
I think you should be able to have lights up all year if it pleases you, but I'm not in a position to point any fingers. Our house is still bedecked with one strand of old school amazingness and a snowman on the front door. To our defense our holiday season just ended on Saturday.
We'll take them down most likely this weekend. But no one has been so nosy as to ask us to do that.
When do you take down your lights (if you decorate) and how long do you thing is "too long?"
