LOCKED

Without saying anything back, I went upstairs, my mother following me. As soon as I got in my room, I heard her lock the door behind me. I sighed and sat down on my bed. Why did she always do this? Locking me up in my room, whenever I got mad or annoyed. She didn't want to risk anything, she always said to me. I was getting pretty pissed off hearing it over and over again. I clenched my fists at the thought. Suddenly I heard a 'thud' noise. I looked behind me and saw that my books fell off their shelve. Feeling frustrated, I put my hands on my head. Why is this happening to me?! Why am I always locked up?
