I had just returned after a long, draining day at work. I was utterly exhausted — all I wanted was to slip off my shoes, flop onto the couch, and maybe even nap for a little while. I approached the door as usual, automatically reaching for my keys… when I spotted something unusual.

A small coin was stuck in the lock. Very small, nearly unnoticed, but clearly out of place. I live alone, and I certainly hadn’t left anything like that there.
At first, I assumed it was a coincidence or someone’s silly prank. But then a cold shiver ran down my spine — what if it wasn’t accidental?
I swiftly withdrew my hand from the door handle and followed my gut instinct — I called the police. While waiting, I desperately searched for information. And I discovered something terrifying… 😱😱 If you ever encounter something like this, be cautious 😲 Details in the first comment 👇👇

📌 It turns out this is a classic tactic used by scammers and burglars.
They insert a coin (or a thin piece of plastic) between the door and the frame — typically near the lock.
The method is simple: if you’re home, you’ll open and close the door, and the coin will fall out. But if it remains there for several days, it indicates no one is home — making the property a target for burglary.
It’s a quiet and nearly invisible way for thieves to determine if someone is away on vacation or a business trip. That’s how they choose their “victim.”

⚠️ What you can do to protect yourself:
Always inspect your locks and door edges, even if you live in a secure area.
If you plan to be away for a while, ask a neighbor to watch over your home.
Install security cameras or at least a dummy alarm system.

Pay attention to small objects near your door: paper, coins, unusual marks.
I still don’t know if someone was genuinely plotting to break into my apartment… but since then, I’ve been far more vigilant. I recommend you do the same.
