Why am i the one!!

Today was shit!! My sister just got back from camp and my father cared more about her than me!! I told him that i want a iphone... I told him twice.... He did not intend to buy me one!! And whats more he cared about my sister and ask me to buy food for her!!! WTF!! It is not the first time... Have he even cared about me once?!?

Why am i the one?!! So damn unfair!! Am I his son??
