"Time off"
Smith goes to see his supervisor in the front office.
"Boss," he says, "we're doing some heavy house-cleaning at home tomorrow, and my wife needs me to help with the attic and the garage, moving and hauling stuff."
"We're short-handed, Smith," the boss replies. "I can't give you the day off."
"Thanks, boss," says Smith, "I knew I could count on you!"
