A woman was driving in Northern Arizona when she approached a woman who was hitchhiking. Welcoming the opportunity for a travel companion, the driver stopped and, in the course of their talk, the woman glanced at a small bag on the front seat.
“If you’re wondering what’s in the bag,” the driver said, “it’s a bottle of wine. I got it for my husband.”
The hitchhiker thought for a while, nodded several times and said, “Good trade.”
