Accomplice: It was him (points)
Perpetrator: It was an accident.
But the perpetrator has made the mistake of running straight home so I ring the door bell.
I am choking with fear, rage, whatever, but trying not to show it. Poor woman. She is skinny and grey and has scabs on her face. A drug user? More than likely. She apologizes and thanks me for telling her and says she'll ground the perp. I thank her back. As I walk away I hear her screaming at him and feel sorry for them both.
