Life, Me, And My Brother

I saw him, last night. He thrashed himself. I didn't knew why he was doing that. He told me that everything will be ok, that I don't have to worry about anything and because he his the only person that I have in this world, in this life. I promised him that someday we will find our happiness.
At night, when he think I'm sleeping, he goes out from his room into the "Dark Room", that's how I call him. 'cause in the moment that you get into this room, you remember everything that happend in your life, especially the most terrible things. And.. I didn't want to remember anything from what happend. How my mum died, how my father tortured us, everyday, every-second, how I left my friends there, without saying goodbye. I wanted to forget, everything.
But.. it was impossible because when I'm looking in this flat, I know we are not going to stay here for a long time because in the moment that the police pass here we are going to run away, again. The police think that we killed our parents, but it wasn't like that, they don't know anything from what happend.
My father always tortured us, my mother was trying to help us but in the moment he saw that, he (my father) throw her on the floor and hit her until she died, then I began to scream; Mum! Mum!!! I hoped she could hear me but she didn't say anything, she just.. lay there, on the floor with open eyes, and alot of blood coming out from her head. My father killed my mum and then he killed himself. that's the truth. But we run away, and the police think we did that. We run away because we didn't knew what to do, we were afraid. And since that moment, my big brother have became the only thing I have in this world so everything that he said to do, I did without asking any questions.
We are escaping almost five years. and now, we are living in this small flat almost two months, the most longer time we have stayed in one place.
