On an ordinary Tuesday morning, I started my job as a postal worker in a small town in Montana. For 15 years, I had walked the same route, knew every house, every mailbox. But this day was different.

House number 247 – a Victorian building that had been empty for years. The old mailbox, usually full of cobwebs, contained a cream-colored envelope. It had no address, no return sender, just a faded red seal.

My hands trembled as I touched the envelope. In 15 years, I had never seen mail here. The paper felt old, at least 50 years. When I turned it over, a small note fell out: “Dear Sarah, if you find this, open the envelope on March 15, 2025, at exactly 3:47 PM.”

A Mystery Mailbox That Changed Everything

Today was March 15.

The clock showed 3:46 PM.

My heart was racing. The letter in my hands grew heavier. The old clock in the post office struck the hour. With trembling fingers, I broke the seal.

The Unexplainable Discovery Inside the Mystery Mailbox

Inside the envelope was a yellowed photograph of myself, taken today, at this moment, opening the letter. On the back, in faded ink, it read: “Sometimes we must change the past to save the future. Don’t go home today, Sarah.”

My legs went weak. The photo was impossible. The handwriting – I recognized it. It was my own.

I called in sick and spent the night at my sister’s house. The next morning, I learned that a gas leak had caused an explosion in my apartment building. The only casualty was my neighbor’s cat, who had somehow gotten into my apartment.

In my mailbag, I found another envelope. Inside was a single sentence: “The future thanks you, Sarah. Now burn both letters.”

To this day, I keep checking house number 247’s mailbox, wondering if I’ll ever receive another message from myself.
