Your standing in a living room, facing towards a mirror, now slightly turn to your left. In-front of you you can see a open door, walk to the open door and exit the room,  in-front of you you can see another open door, walk to the open door and exit the room. Now walk straight, to the left you can see a staircase,  in-front of you there is another open door, walk to the door and stand at the entrance of the door, that's your end point.
