When Oregon man Jacob Fry lost his license, he figured it was gone forever. Then, a few days later, he received the license in the mail along with this letter:

The letter was from Steven Cruthirds, an 11-year-old boy with autism. Steven explained that he'd found Jacob's license on the street and thought returning it would be "the nice thing to do."
