Sally was driving home from one of her business trips in Northern Arizona when she saw an elderly woman walking on the side of the road.

As the trip was a long and quiet one, she stopped the car and asked the woman if she would like a ride.

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

Resuming the journey, Sally tried in vain to make a bit of small talk with the old woman.

The old woman just sat silently, looking intently at everything she saw, studying every little detail, until she noticed a brown bag on the seat next to Sally.

‘What in bag?’ asked the old woman.

Sally looked down at the brown bag and said,

‘It’s a bottle of wine. I got it for my husband.’

The old woman was silent for another moment or two.

Then speaking with the quiet wisdom of an elder, she said:

‘Good trade…..’
