I'm one too that hardly ever locked the house. Never locked the truck. Never locked the car till two things happened. The newer vehicles have an automatic door lock when you put it in gear. Our Malibu can't be driven without locked doors. Second is living around Atlanta we have a portion of the population that are on the government hand out system. They pretty much have the feeling what's mine is theirs for the taking. So they have something they call 'carjacking'. You folks that live where there are no locks needed, that term "carjacking" just means you can be sitting at a traffic light and some bottom feeder sticks his cheap handgun in your ear and takes you vehicle. I say this 'cuz I know in you land of peace and tranquility this is foreign term to you. Some of us had to contend with this. Now I know insurance will replace the truck if it's destroyed, but after they've had days of crack party's and sex parties in your vehicle, who would want it back? Yes, I do realize I can move. And I have twice, but these sorta people just keep spreading. So all of you with no locks and have no need for them, count you blessings. All of just can't live in utopia. So we have to find ways to look after ours. Lord knows I do pray these low life's would stop their ways, but here at least it's just getting worse. Y'all count yourselves blessed that you live in a land of peace without these government pampered bottom feeders to worry with. But the best part, you do have need to lock anything up. How fortunate you are.
