Imagine you're in a room. This room is restocked with supplies of food, exercise machines, and various forms of entertainment(no internet, though.), enough to let you live the rest of your life.
Now imagine you're stuck there with the person who posted last.
If you kill them, you can leave.
So just state if you would kill the person above, or stay with them in the room forever(you can go into detail if you want.), or even, the ultimatum of taking your own life.
tl;dr: post if you'd kill or spend the rest of your life with the user above.
