price already paid

"Imagine that someone purchased an appliance for you and also paid for a warranty to take care of any repairs. Imagine that at some point the appliance breaks down and is in need of repair. You don't know about the warranty, so you forgo the use of your appliance because you can't afford the repair. Then imagine the giver's despair when she discovers that you have not accessed the provision she had already paid for. Think of her sorrow at knowing that you have scraped by when she already paid the price that would guarantee you exactly what you needed."
