Don't teach your wife project management

My wife Christine asked me for status on checking the car tires for proper air pressure.
"It's a recurring task ... it needs to be done every month."
"You know you consume more gas when the pressure is low."
"Can I count on you to do it without follow up from this point forward?"

My responses:
"Mark it zero percent complete."
"What's the dollar impact?"
"No you can't. Welcome to my world."
