I told her numerous times its not a good idea but she never listened! Then I told her publicly on her car photo that she should at least wipe out the plate number, which created a long trail of comments where basically all her friends thought I'm weird and creepy and why would I be warning her (perhaps I want to commit some crime??). No amount of explaining helped. Even telling cops will tell her the same thing got me bunch of her "friends" answering "you ain't a cop, bro". And then one fine Friday I saw her posting they leaving for another state to visit family. Boy it was a discovery when they come back Monday morning their house was cleaned out from every possible valuable belongings. And thieves must have came with a large enough truck to fit that 85" TV screen.
Not long after she removed me from her FB even though I never told her "told you so".
The bottom line is I don't believe people will learn not to give a clues online and I think in these days of age it should be an hour mandatory lesson at the school what NOT to post online.
