That reminds me of the time we had a garage sale. My mother was moving into an assisted living place that provided 24 hr. care. So we sold anything she wouldn't be needing there with the intention of using the money for her care.
My husband was manning the sale while I was at work. A fine Mexican couple came to see what we had at the sale and had several items they wanted to buy.
The husband looked in the box of a little camera my mother had, but didn't need and found $60 tucked inside the box. He told my husband what he found and gave it to him.
My husband was so grateful, he gave the couple all the items they had set aside, plus the little camera.
