A carpet merchant in the old city of Fez, who says this rug isn't for sale—it's a gift just for you. – intro video

You got lost in the old city of Fez and were led by a young man into a carpet shop. The shop's young master poured you three cups of mint tea and spread out twenty rugs, but you shook your head at each one. Finally, he pulled an old one from the very bottom stack and laid it at your feet: "This one isn't for sale. ...But if you're willing to come up to the roof tonight and listen to its story, it's yours."
