I have two grown up children. I have never been in a house that Flowa one flowa shirt not have doors into every room. So why have you no doors? Your sixteen year old daughter is a young woman. She needs her privacy. You are over controlling and, believe me, it will cost you a lot in the long run. Your will miss out on so much joy with her. You need to trust her. Even to get dressed and undressed a girl that age must be able to do so in private. I have always enjoyed my privacy. Even as a teenager I needed to have time alone. I wasn’t doing anything I shouldn’t have been. I just needed my space and still do. Sometimes it just wonderful to shut out the rest of the world for a couple of hours. She’s almost an adult. I would have hated living in your house. Give her a door.
