You need enough time to open the door and make mental notes of everything inside. That 'pffft-clink’ sound the door makes is like a dog whistle — the inhabitants could come running. Once you’re peering inside, you might spot a jar of Ragu spaghetti sauce. In the fridge of a famous cook. How embarrassing."
