About this location

A few stories people tell about this place

1. One morning, a delivery driver noticed something strange: every time he arrived at Serra Mesa Post Office, an old lady in a blue coat would appear out of nowhere and wave him down from across the street. Curious, he slowed down and waved back. To his surprise, she started waving frantically, pointing towards her mailbox. The driver got out, only to discover that her mail had been stuck inside for weeks—she’d been trying to signal someone! From then on, whenever anyone asked about the mysterious woman, everyone just smiled and said, ‘Oh, that’s Mrs. Blue Coat—the one who never misses a chance to help out.’

2. Late one night, a delivery driver approached the Serra Mesa Post Office and heard an eerie humming sound coming from inside. Curious but cautious, he peered through the window—only to see dozens of letters dancing in perfect synchrony on their shelves. As he watched, they seemed to form shapes—a heart here, a smile there. Startled, he knocked on the door, but no one answered. Finally, one letter fell off its shelf and landed right next to him, with a note that read: ‘Sorry for the disturbance, please come back tomorrow.’ The delivery driver shrugged, smiled, and went home, knowing that sometimes even mail has its own schedule.

3. Late one night, a delivery driver approached the Serra Mesa Post Office and saw a faint light flickering inside. As he peered through the window, he noticed an old man in a fedora sorting letters with remarkable precision. Curious, the driver knocked gently on the door. The man looked up, smiled warmly, and said, 'Just finishing up for the day, my boy.' Turns out it was a regular who stayed late every Thursday to help his neighbors with their mail.'

4. Have you ever seen an envelope with no return address but just a smiley face? That's what started showing up in Serra Mesa Post Office mailboxes. One day, a delivery driver found an envelope addressed only to ‘Happy Customer,’ complete with a rainbow sticker and a note saying, ‘Thanks for using our service!’ Turns out, it was signed by none other than ‘The Mailman Fairy.’ Since then, whenever someone receives a mysterious package without a return address, they know to look for the little surprise inside—maybe even a cookie from a neighbor who thought the joke was hilarious.
