This is beyond stupid. A 17-year-old Sydney girl helping her grandmother count her cash savings was promptly visited by two knife-wielding men after she posted photos of the cash on Facebook.

The girl’s mother told the two intruders that her daughter was not home and she didn’t live at that address anymore.

The men searched the house and took a small amount of cash and other personal property before leaving the house.

No one was injured during the incident.

Police are using the incident as a lesson in the dangers of social media, because it apparently takes something like this to realize that reality.
