In China, if your wall is suddenly painted with strange symbols, experienced people will know that this is likely to be a mark drawn in advance by a thief!

There was also a mother in New South Wales who encountered the same thing, which really scared her.

On Sunday, Ms. James, who lives in Ballina on the northern coast of New South Wales, went out to get the mail as usual, but found a small piece of black tape on the mailbox at her door! She found this black tape.

It looks new and doesn't look like it was randomly pasted on!

After realizing something was wrong, Ms. James, who had no idea what to do, posted the incident on Facebook to ask for help:

"You may think I'm crazy, but I just want to ask, I found this black tape hanging on the side of the mailbox, does anyone know what it means?"

I didn't expect that "one stone would cause a thousand ripples"!

She was shocked by the large number of responses from netizens:

Some people also said that, some thieves would scout the area, and leave a piece of tape in the keyhole of other people's doors.

If it is not removed in time, it means that no one is at home, which means "it's time to start"!

What's even more terrifying is that in the two nights after that, Ms. James and her boyfriend could see through the surveillance that a group of people seemed to be surrounding their house for two consecutive nights...

In desperation, they chose to report the incident to the police station first.

In response to the concerns of netizens, Ms. James also said that she would be more vigilant in the next few days! She would also keep the lights on in the yard all night and always have a cricket bat at hand as a weapon!

In addition to thanking netizens for their enthusiastic suggestions, James will also check the surrounding area with neighbors. Of course, they hope that all this is just a prank by children and a mistake, which would be great!
