"Babe, babe, I can explain. You weren't supposed to be home."A character decides to do something mischievous or otherwise verboten under the assumption that they have the house for themselves. Rule of Drama ensures that the spouse, wife or parent, who is believed to be away, will show up at the doorstep when it is least appropriate. Perhaps they forgot something and returned to pick it up or they came back earlier than expected to surprise the character. Whatever the reason, expect a Bedroom Adultery Scene or Not What It Looks Like situation to ensue in front of their eyes.
