My parents try their hardest, there is just something possibly mentally wrong with my sister. I think my sister is some sort of psychopath. She is incredibly strong for a 14 year old girl and can act pretty masculine. I'm starting to suspect her of being a lesbian and having a fetish for fat girls. She loves to burn things. She plays with matches and incense. She once kept poking me with a lit incense and wouldn't stop till I hit her with a barage of punches to the face. She is like a pitbull, when my fist touch her body I felt I was hurting myself more trying to hit her as her body was so hard and seemed to have enough tolerance to the pain to fight back as if nothing was hitting her. My dad seems oblivious to whats going since they get on their best behavior when he gets home or wakes up and he usually makes his plate before they get some and stashes the rest of his food in his room. I'll need to write everything down that they do and read it to him.
