Keep in mind that I'm alone except for the dog being here. I was going to the bathroom and that is right by my room and found the door locked. I knocked on it thinking my little sister or someone was in there. Nobody answered so I went downstairs to the bathroom did my bussiness then came back to my room. Before entering I did grab something just incase someone had come into my house. When I went back to the door it was unluck. Nobody was in the bathroom.
