Get Any Key to Continue
You enter the kitchen as usual, but are struck by something -- the refrigerator. Normally it makes a lot of noise, but it seems to have gone silent at your approach. The bracelets on your wrist vibrate as you draw nearer to the fridge.
Acting on a hunch, you hunch over and look under it. You see something... strange. It is not a key, but the only thing stopping it from being a key is the fact that it is not a key, if you catch my meaning.
You decide that this conceptual absence of a key might come in handy, so you figuratively grab it and stuff it into one of your imaginary pockets.
