Good grief it has been SO long since I had to deal with this, it had actually slipped my mind. This one never made sense to me either. In my family we did the Friday thing too, but we did one other thing that was technically allowed. We celebrated my parents wedding anniversary, which was Dec 31st, just like Christmas minus the decorations. We'd have a big dinner and exchange gifts. My parents loved it because they got all the after Christmas sales. We never advertised it, probably because no one wanted to have them put a stop to it.
And welcome to Mountainsnowrider and Sahara! Great first posts.
