If you get a package in the mail not addressed to you, and it's not your neighbor's, just hold on to it and see if anyone claims it. DO NOT SCAN ANY QR CODE associated with the package!! (I don't scan any QR codes after getting hacked at a local restaurant a couple of years ago when you had to order from the QR code even though you were SITTING RIGHT THERE! )
Remember the old saying "If it sounds too good to be true, it is."? These days of computer intelligence and access, that saying has never been more true!
