sister?

why do you always treat me like your self maid sister? who do you think am I to you, sister?.. do you think of me as your dearest little sister, or you think of me as a stranger whom only help you due your problems? you make me annoyed, and so do you make me mad.. but yet I still love you like a relative's dead love. I know you lie about your actions, your words and everything you act innocently. but I am not sure if I do love you, as a relative of yours, why do you make me feel like this, sister?..
