About this location

A few stories people tell about this place

1. One morning, a delivery driver noticed something peculiar in the mail sorting area: an old, dusty envelope addressed simply to ‘The Next Resident.’ Curious neighbors began finding similar envelopes around town, each bearing different names and addresses. Soon enough, everyone was checking their mailboxes for mysterious letters. A regular started joking that maybe it was time to move out and let someone else live in his house—after all, why not? Finally, one day, the envelope addressed to 'The Next Resident' arrived at the postmaster's desk. With a laugh, he opened it and found inside a note reading: "Dear Kendall Square Post Office, please forward all future mail to 123 Main St."}

2. One day, a delivery driver noticed a strange package on the postal counter. It was addressed simply to 'The Busy Bee,' with no street number or city. Everyone laughed it off as another prank until… Finally, someone dared open it—inside was just a small note reading, ‘Meet me at Kendall Square Park tonight.’ The next evening, everyone gathered there, curious and amused. Turned out it was an invitation from a local artist who wanted to host an impromptu art show.’

3. In Kendall Square, a delivery driver once overheard a regular saying, ‘Did you see what they did with those envelopes today?’ Curious, he looked up and saw that every letter had been meticulously decorated with tiny stars. The delivery driver grinned, realizing it was just an elaborate prank by their friendly neighborhood mailman. From then on, whenever someone asked about the starry letters, everyone would wink knowingly—except for one confused tourist who kept asking where they could buy such decorative stamps.

4. One afternoon, a little girl asked her mom, ‘Why does that postman always wave at us?’ The mom replied, ‘He probably just likes our house.’ But then one day, he waved and winked—was it really just a friendly wave? That night, the little girl pretended to be a postman herself, waving and winking at everyone she saw. Her neighbors thought it was adorable—and so did the real postman when he delivered their mail the next morning.
