You're right it's not understandable. I too don't wish ill on neighbors but figure my layers of security just need to be better than theirs so the predators will take the easiest bait. Some thieves/predators are better/smarter at their job than others. Thieves especially vary widely in motivation and intelligence - some motivations make them stupid or they just have a completely whacked way of thinking - like they might not use a gate - they just hop a wall. Or they just had an extra hour of time and happened to be right where you are...etc.We have the chain link fence with privacy slats and a smaller block wall inside that, but if you're tall enough you can see over the fence, unfortunately.
Years ago I caught a guy checking out the contents of the yard. I was sitting in a chair and quietly reading and he didn't see me. I stood up and asked him what the $#%^@ he thought he was doing. He jumped and his eyes got big as saucers and he mumbled something about yard work. I told him we didn't need any and he needed to move along. He walked around to the front of the house and kicked over our mail box.We didn't have much stuff in the yard back then and we figured it was just a one-off. I think we should have gotten a shed then. I know a locked shed isn't a perfect deterrent but it helps when things are out of sight.
What kills me is that most of our neighbors don't have garages either and they store all kinds of things in their yards out in the open. They don't have dogs AND they have working gates that open right into the alley (our alley gate is covered and doesn't open). So WHY did the thieves choose us??
(Edit: I don't wish ill on any of our neighbors! I'm just trying to understand something which is probably not understandable.)
