It’s 2023 now. Five years ago, Don and Nancy moved into their home. They bought a mailbox that looks just like their house. He didn’t realize that the empty box would be that attractive for a doll couple!

One spring day, Don went out to get the mail. He found a pair of dolls inside. There was also a puzzling note: “We’ve decided to live here,” it read. “Mary and Shelley.” Don went door to door to ask his neighbors. But no one knew anything about the dolls living in his mailbox. Don thought about throwing them out, but something inside him told him not to. That turned out to be a good idea, because soon the dolls got even more comfortable! There was a painting on the wall and some beautiful furniture in the room. Mary and Shelley even got themselves a dog. Gradually, Don started to look forward to seeing what dolls would add next.

One day, he turned to the Internet to see if anyone had ideas about the dolls’ owners. No one did. Every holiday, he’d share the dolls’ new clothes, decorations, holiday gifts and other things in his mailbox. “People were saying, ‘This is so much fun to read. I was ready to get off, but this makes me want to stay.’ ”

Don and Nancy are still no closer to knowing who’s behind the mailbox trick. But they said it’s a “good positive thing” . “I look forward to new things being added to the mailbox,” Don said.
