As we get closer to Christmas, the citizens of Party Town begin to flee. Festive occasions thin out this time of year.

• Nigerian President Olusegun Obasanjo tribute. Waldorf-Astoria Hotel, 301 Park Ave., nr. 49th St., 6 p.m. Hosted by Andrew Young, former mayor of Atlanta and ambassador to the U.N. Black tie or national dress required. Go with national dress; black tie is so dull and drab. Sponsored by Chevron!
