Ladies it doesn't matter if you live alone or even if you live with someone. Here's some advice from a Security Officer in Atlanta, Georgia who is sort of internet famous for being tough on criminals. What do you do when a creepy guy comes to your door and wants to come in? Just push play...

You can go to his website and pay that money if you want to ... or just record your actual brothers / fathers / any tough sounding guy voice to your computer. Same principal right?
