You go to the front door, and Nicole hides inside the house. Richard rings the doorbell, and Marc answers it. "Oh, it's you. Where's my sister?"
Richard points down the street. "We were being chased by an angry dog, and now she's gone. I don't know where she is!"
Marc looks worried. He and his friends put on their shoes and run outside. You lead them around the corner and then run back to the house. Nicole lets you in and you lock them outside.
You spend the rest of the night enjoying all the candy. They spend the rest of the night banging on the front door, until Nicole's parents come back.
THE END
