The game was the same as every year. Rachel could have called it in July, if she’d wanted. For every age-inappropriate costume that knocked on the door of their no-kids party—six-year-old sexy nurses, second-grade saloon girls—Bill had to do a shot. For every comic book or television character, Nalene had to do a shot. Usually David got drunk off ethnic-insults-on-parade—kids in headdresses, kids-as-pimps—but three months ago his girlfriend “Carrie” had given birth to a bouncing baby boy, so he wasn’t even at the party this year.
