You are in a room standing in front of an open door with a toilet to your right.  You are going to exit this room.  You are going to make an immediate right and you are going to see in front of you a drum set.  You are going to walk towards the drum set and once you have taken one step towards the drum set you are going to take one step back and this once step will be taken in the direction of the wood railing.  And once you have made that one step you are done.
