Sally was driving home from one of her business trips in Northern Arizona, when she saw an elderly Navajo woman walking on the side of the road. As the trip was a long and quiet one, she stopped the car and asked the Navajo woman if she would like a ride. With a word or two of thanks, she got in the car.

After resuming the journey and a bit of small talk, the Navajo woman noticed a brown bag on the seat next to Sally. "What's in the bag?" asked the old woman. Sally looked down at the brown bag and said, "It's a bottle of wine. Got it for my husband."

The Navajo woman was silent for a moment, and then speaking with the quiet wisdom of an elder said, "Good trade."
