 Screwdrivers, saws, heck, you leave a ladder outside and you've got a window open on the second story and you're away for the weekend and somebody's like, ooh, right away I can get right into your house. It's like handing them the keys, right? Seriously.

You'll be surprised to learn how many break-ins happen just because of an easy opportunity. So don't give them one.
