The Mysterious Door Knock

Last Sunday evening, I was home alone when suddenly I heard knocking at the front door. I looked through the peephole but saw nothing. I opened the door, and again, there was no one there. Maybe some guy is making fun of me, or maybe it was an illusion. I came back to the TV, feeling a bit uneasy.

After a while, the door rang again. As it was before, no one was there. I shouted out, "Don't do this again, it's not funny!" Still, the knocking persisted, and I began to feel a strange sense of dread. I grabbed a flashlight and went to the door, ready to confront whoever was outside. But when I opened it, there was no one.

Panicked, I called my parents, but they were all out. I was all by myself, and the mysterious knocking continued. I decided to investigate further. I checked the security camera, but there was no recording. It was as if the knocking was coming from nowhere.

Finally, after what felt like an eternity, the knocking stopped. I was relieved but also puzzled. I never found out who was knocking at my door, and it remains a mystery to this day. That experience taught me to be more cautious and not to jump to conclusions without understanding the situation fully.

建议：
