Just sent the last Christmas houseguest off to the train station, and am deep into a day of doing chores with a zen attitude, relaxing, taking the time to write letters to far-away friends. As the song goes, What are you doing New Year's Eve? I'll be at home, for dinner and an evening of playing cards with friends, if we get around to it, informal in the sense that I don't mind who stops in while they're out. Planning the menu, I asked my sister what her friend, coming up from Maryland, drinks. "Oh, she's fine with champagne."
