Advent Aproaching

The only way to know what’s behind the door is to open it, be it on a cupboard, a wall or even a trapdoor. Though, these days, there’s been a few advances in this field. We’ve put windows in. It may make the door less secure but at least you can see what’s coming. This then involved into the peephole, where you can see one side, but your counterpart can’t see the other (unless you’re unlucky enough to be the counterpart). And now you have the camera doorbell and you can choose whether or not you want to interact with your caller. But when you interact with a bit of cardboard, it hardly seems worth it. If you really wanted to, you could ask someone else who’s got the same version, but it takes all the fun out of it. But you probably know what’ to expect behind a cupboard door anyway.
