Before Holden arrives, what were Mr. and Mrs. Antolini doing?

Mr. Antolini was drinking a high-ball. Mrs. Antolini was making coffee.

He had on his bathrobe and slippers, and he had a highball in one hand. He was a pretty sophisticated guy, and he was a pretty heavy drinker. "Holden, m'boy!" he said. "My God, he's grown another twenty inches. Fine to see you."

He turned around and yelled out to the kitchen, "Lillian! How's the coffee coming?" Lillian was Mrs. Antolini's first name.
