Bob was driving home from one of his business trips to northern Arizona when he saw an elderly Navajo man walking on the side of the road.

As the trip was a long and quiet one, he stopped and asked the old Navajo if he would like a ride.

With a silent nod of thanks, the old man got into the car.

Resuming the journey, Bob tried in vain to make a bit of small talk with the Indian; however, the old man just sat silently, looking intently at everything he saw, studying every little detail, until he noticed a brown bag on the seat.

"What in bag?" asked the old man.

Bob looked down at the brown bag and said, "It's a bottle of wine. I got it for my wife."

The old Navajo was silent for another moment or two. Then, speaking with the quiet wisdom of an elder, he said:

"Good trade."
