A Boulder, Colo., couple found and returned a plain envelope with $800 inside back to its owner.
While taking a walk, the couple found an envelope with the cash lying on a sidewalk.
They left a note with their e-mail address in hopes that the owner would write them.
The note said, "Lost $? Found it here July 31st," The letter gave an e-mail address to send a description. The person promised, "I'll get it back to you."
And when the owner discovered he lost the cash, he retraced his steps.
Eventually he found the note, contacted the owners and retrieved his money.
The couple told Denver's ABC News they knew it was the right thing to do.
