We all love Christmas. But you, my dear, may have dampened our holiday spirits permanently. It's the beginning of April, and your dining room still looks like "Miracle on 34th Street," except the scents of pine and cinnamon have faded into the smells of my great-grandmother's attic. Your lovely Christmas tablescape doesn't really convey the holiday spirit when it's completely full of dust and dog hair. Cotton batting makes good snow, and eventually it makes a great rat's nest. Next time? Consider putting away the decorations when you stow your Johnny Mathis Christmas album.
