So we're never safe then?
Shatter my cosy little world why don't you?
I'm going to hide under my bed tonight!
No one is safe because accidents do happen. It's been said people are killed more near there home than they are away from there home, because they let their guard down. An experienced thief will not attempt to rob someone who appears to be alert, they go for those who aren't.
The truth is that I seldom lock my house or car.
I am even frequently unlocked at night.
I live in a town of 2,000.
To be fair, I wasn't like that when I lived in a city of 50,000 though.
I certainly wasn't frightened though, I was just more concerned about being ripped off.
