I'm tired and there is no milk.
No milk means no coffee.
I have no car.
Well, I do have a car but it is getting a new bumper.
I may have been involved in a car park bingle.
It would be my first accident, if such a bingle occurred.
Tired. No coffee. No car.
So no car to get the coffee to stop me being tired.
No coffee to stop me being tired and get me to walk to the shops.
