The Story:

A few months ago, I was out with friends and lost track of time. When I finally decided to go home, the streets were almost empty. Luckily, I found a taxi, and the driver, a tired-looking middle-aged man, agreed to take me home.

At first, we talked about normal things like work and the weather. Then, out of nowhere, he asked, “Do you ever feel like someone’s watching you when you’re home alone?” I laughed, thinking he was joking, but he didn’t laugh. He just stared ahead and said, “I used to feel that way when I lived on your street.”

I got a strange feeling but didn’t say anything. When we got to my place, I went to pay, but he shook his head. “No charge,” he said quietly. “Just be careful tonight. Lock your windows.” Feeling confused, I thanked him and watched him drive away. The next morning, I saw something that made my heart race: my bedroom window, which I always lock, was wide open.
