He took the cigarette pack from his shirt pocket and hit it against the heel of his hand until two or three cigarettes were higher than the rest. He pulled out the highest, then shook the pack so the other two descended again and put it back in his pocket.

The coal of the dying cigarette flared and lit the new one. With a jerk he took butt from his mouth and snuffed it in the already too full ash tray. He brought the new one to his lips and inhaled deeply. His fingernails and the tips of his fingers were stained yellow.
