About this location

A few stories people tell about this place

1. It was just another day at the East Cambridge Post Office when a delivery driver noticed something strange. Every morning around 9 AM, an old man in a tweed suit would arrive and carefully place three identical packages on the counter. The packages were always wrapped in brown paper and tied with string, but never labeled. The driver asked him once what they contained, and the old man simply smiled and said, 'Just some letters from my friends.' After a month of this routine, everyone at the post office started calling him ‘Mr. Secret Mailman.’ One day, after he left, the curious staff opened one package—inside was nothing but crumpled-up pieces of paper. To this day, no one knows why Mr. Secret Mailman delivered empty packages every morning. But the neighbors still joke that he’s sending messages from beyond the grave.

2. At the East Cambridge Post Office, every morning begins with an unexpected announcement over the intercom: ‘Ladies and gentlemen, your mail has arrived… from the future!’ One day, a regular noticed that his package was addressed not only to him but also to himself ten years ago. When he opened it, there was just a note saying, 'Sorry for the mix-up!' A delivery driver later admitted it was their way of keeping things interesting.

3. A regular was sorting through his mail one afternoon when he noticed something peculiar: every letter addressed to him had been crossed out and replaced with someone else’s name. Confused and amused, our regular approached a nearby delivery driver for help. The driver just shrugged and said, ‘Hey, it happens here sometimes—maybe you’re just getting everyone else’s junk mail!’ With that, they both laughed, and life in East Cambridge continued as usual.

4. At the East Cambridge Post Office, every morning starts with a routine check of the mailroom shelves. But one day, a regular found something unusual—a package addressed to ‘The Fastest Mailman Alive.’ Curious eyes turned as everyone waited to see if it would actually be delivered instantly. As the day wore on, no mailman dared claim responsibility for such an impossible task. Finally, an old delivery driver joked, ‘Maybe it’s addressed to Santa Claus!’ Everyone laughed, and soon after, the package was quietly filed away in the lost-and-found section. Since then, whenever someone asks about the fastest mailman alive, they smile and say, “He must work here.”
