A saleswoman is driving toward home in Northern Arizona when she sees a Navajo woman hitchhiking. Because the trip had been long and quiet, she decides to stop the car and give the Navajo woman a lift.
During their small talk, the Navajo woman glances surreptitiously at a brown bag on the front seat between them.
“If you’re wondering what’s in the bag,” offered the saleswoman, “it’s a bottle of wine. I got it for my husband”
The Navajo woman is silent for a while, nods several times and says, ”Good trade.”
