About this location

A few stories people tell about this place

1. Late one night, as a delivery driver approached Highland Hills Post Office, he swore he heard laughter coming from inside the empty building. Curious, he peered through the window and saw nothing but shadows dancing on the wall. Suddenly, an old letter fell from above, hitting him squarely on the head. Startled, he rushed in only to find a regular smiling back at him, holding another envelope and saying, ‘Mailman, your shift starts now!’

2. A regular customer once asked the clerk, ‘Do you ever close on Wednesday?’ The postal worker shook their head and replied, ‘No, but sometimes mail gets delivered in the strangest ways.’ One day a delivery driver arrived with an unusual package. He said, ‘This is for Highland Hills, but it’s addressed to nobody.’ Everyone laughed until they saw the return address: ‘To whoever finds this—please deliver.’ A few days later, a neighbor popped into the post office and asked curiously, ‘Did y’all receive that mysterious package?’ The clerk smiled mysteriously and answered, ‘It finally got delivered—on Thursday!’

3. A curious neighbor noticed that every Tuesday afternoon, mailboxes around Highland Hills Post Office mysteriously opened themselves. It turned out that a delivery driver, known for his love of practical jokes, was blowing into tiny whistles hidden inside envelopes. The neighbors started leaving him boxes of cookies as thanks for the weekly serenades.

4. One morning, a delivery driver grumbled under his breath, ‘Why does it always rain when I’m delivering packages here?’ Just then, an old lady approached the counter with a smile and asked for stamps. The driver muttered again, but this time he noticed she was wearing a bright yellow umbrella that matched her rainbow-colored hat perfectly. With a chuckle, he thought, ‘Maybe today isn’t so bad after all.’
