So, it's less than three weeks before Christmas. Friday night. Friends are winding down from their work week, decorating the tree with the kids, and maybe getting ready for a Christmas party. I just learned of my husband's affair. I picked up a card I found in his gym bag. I read the cover and thought, "Wow! This must be my Christmas card." But I didn't put it down, and the surprise was on me. It was from Karen. Karen? Who's Karen?
