SISTER and FRIEND are sitting on couch upstage left, having just finished a scary movie. The house is dark.
FRIEND: Sebastian, can you get me a glass of water?
*enter SEBASTIAN, who enters stage right, turns on all stage lights, and exits stage left*
FRIEND: Seriously.
SEBASTIAN: Hostile mobs don't spawn in light.
FRIEND: Fine, you ass.
*FRIEND stands up and walks downstage right for water when the curtains on the left side move, revealing SEBASTIAN with fingers under fusebox switches*
You can guess what happens.
