Recently, I experienced a wonderful lesson in how little things still mean a lot. My brother, mother and I live in a very rural district on the Big Island of Hawaii. Our farm is at least a dozen miles from the most basic of services. Consequently, we take weekly trips to COSTCO to procure fuel and supplies. About a month ago, we'd finished loading up the SUV and prepared to leave. As I settled into my seat, I glanced down at the roadside, when a piece of paper caught my eye. I picked it up and read it carefully. Instantly, I was grateful I did. The form turned out to be a receipt from the State Motor Vehicle Division, documenting the owners' payment of their Vehicle's Registration fees. Quickly, I put myself in their shoes and figured: no one would throw this out, especially if it was current. I also looked over the form for contact or any personal data, perhaps a license tag or telephone number. But that seemed impractical. Although the form had been born on the wind, where in the busy, crowded parking lot would I find the owners? Had it been lying there for a few minutes or a week? So I checked the date, the fees paid, noted the names of the owners and pocketed the receipt. Recalling the parable of the Good Samaritan, I concluded that the best and easiest step to take was to put the form in an envelope addressed to the couple and send it to them by post. Further, I imagined how crazy I'd be if I had misplaced my receipt. Much easier to attempt returning it than to leave them angry, upset, etc. over the loss. By the end of the week, I received a beautiful thank-you letter from a very grateful and happy couple containing a hand written message and a gift card to use at any Starbuck's. In her note, the wife explained how a gust of wind snatched their receipt from a pocket in her car's passenger door. They had panicked and searched crazily for quite some time before giving up. It felt great to know I'd helped someone avoid a major loss by doing something that at first glance seemed minor or even unimportant.

it was useless for him he knew the owner was upset about losing it the owner asked him to do so he knew the owner would reward him for it
