Who i am?

You are saying, who i am?
you are the buddy who given reason to fight.
you are the buddy who told my mistake is right.
you are the buddy who spread pain in my lovely life.
once pass the time of my need,
you are saying , who i am?
you always plays you boat in tears of my eyes,
you never sunk in , so i never stop tears of my eyes,
i suffer all pain only, but given you lovely surprise,
you always crossed you limit of greed,
you are saying, who i am?
really! you don't know, who i am?
