What if he's onto something though? It stops one way they can see you, so it's not totally crazy. Better than doing nothing at all.

Totally get that, my old stamp collection was basically organized hoarding too.

Tell you what, I spent a whole weekend once trying to shim a door frame because my door wouldn't latch. I was convinced the whole house had settled. Brought out the level and everything. My wife finally asked if the deadbolt worked, and when I tried it, the door locked solid. The regular latch was just worn down to a little nub. I'd been fixing a problem that didn't exist. Felt like a real genius that day. Sometimes the fix is so dumb and simple you just stare right past it.
