An actual UPS driver, not one of the two we regularly see, tried my door knob the other day. My front door is always locked, and can't in any way be confused with a porch door, it clearly goes directly in to the house. I'm sitting here with my son, and the door knob wiggles a couple of times. Then a hard cop kinda knock. I looked outside, and it's a real UPS van, guy in full uniform but absolutely not one I've seen before, walking away. He left the packages on the walkway. If that door hadn't been locked, he'd have felt the iron-clamp jaws of my hound dog on his face.
