My teenage daughter once came home two hours past curfew. I heard the door, heard her carefully remove her shoes, and heard her slowly walk past my room.
I pretended to be asleep. She had been struggling socially and had finally been invited somewhere. I knew I should enforce the rule, but I also knew how badly she needed that night. The next morning, she gave me an unnecessarily detailed lie about being home on time. I gave her an unnecessarily serious lecture about trust while secretly knowing everything.
