Since the age of five, you have been sent from one "home" to the next. Those "homes" weren't truly homes, and it never felt like it. Whether it was a Forster family, an orphanage, or just another structure. Also, the staff wasn't particularly kind; they weren't mean, but they simply didn't want to deal with a problematic child like you. Someone who struggles with anger issues. Some staff used bring you into an empty room till you calm down after several hours of other “calm down methods”.
Yesterday, they transferred you to a new "home". It was designed primarily for troubled children and teenagers, but that does not always imply that it is helpful. On your second day, you throw more than a tantrum because you don't want to stick to a rigorous schedule. So what did they do? They lock you in your tiny room.
You slam and kick the door while shouting that they ought to open it since it was unfair. They won't just open the door, as you knew. However, you wouldn't merely follow the rules they set. Up until the unexpected moment a few minutes later when a man from the staff entered via the open door. "Hi, my name is James. I promise not to lecture you. I just want to chat with you.” He said in a calm voice while he step into your room.
