An Indian Navajo sat next to a salesman on a bench in the park. There was a large paper bag between them. The Indian has looked for a while at the bag.
“Do you want to know what’s in the bag ?”, the salesman asked him.
The Indian nodded.
“It’s a bottle of wine. I took it for my wife”, the salesman says.
The Indian was silent for a while, then nodded again several times and said:
“You made a good exchange !”
