About this location

A few stories people tell about this place

1. One morning, a delivery driver noticed something unusual on the post office parking lot—a small package wrapped in brown paper with no return address. Curious neighbors started stopping by every day, hoping it would be theirs. Finally, after weeks of waiting, an old lady picked up the package, excitedly unwrapping it to reveal… another note saying ‘Not yours.’ The whole town erupted into laughter when she exclaimed, ‘Well, I guess it’s mine now!’

2. In the early afternoon, a delivery driver pulled up to Porter Square Post Office and noticed an odd sight: someone had left a bicycle propped against the wall, complete with a neatly folded letter attached to its handlebars. The note read: ‘Dear Sir/Madam, please hold my package until I get back from cycling.’ The delivery driver shook his head, smiled, and took the bike inside. An hour later, a regular customer walked in, panting slightly, and asked if they were holding anything for Mr. Johnson. Everyone laughed when he explained that he’d been out on his daily ride.

3. In the late afternoon, a delivery driver pulled up to Porter Square Post Office and noticed an old cat sitting on the mailbox, staring intently at the mail slot. As he approached, the cat leaped down and began following him inside. Surprised but amused, the driver asked a nearby neighbor if they knew whose cat it was. With a smile, the neighbor replied, ‘Oh, that’s just Mr. Whiskers. He thinks he works here.’

4. One day, a delivery driver pulled up to Porter Square Post Office and asked curiously, ‘Who’s been using our mailboxes as an art gallery?’ Upon closer inspection, they found that someone had been sticking colorful envelopes into slots, creating abstract patterns on the walls. Turns out, it was just a neighborhood artist trying to brighten everyone's day with their unique expression. Since then, Porter Square Post Office has become known for its occasional mailbox murals, adding a touch of whimsy to everyday life.
