Father, not dad

you're my father, not my dad, dont get them mixed up, when I looked at you I wanna throw up. you don't know what instrument I play, you don't even know if im ok. I love you of course, but you only love the whores. you don't know about the things that go on in my mind, but you'll perk up when you're phone has chimed. you make me feel like a burden, you don't care when im hurtin. you act like youre a friend, but youre not even that in the end.
