Will Always Be My Sister

She constantly fights with me,
But always my guardian angel.
She is my best rival,
But she is my best companion.
She is the person I want to dodge,
But she is the first person who got my back.
She is against all odds,
But always be my partner in crime.
She is the person I envy the most,
But the person who inspired me the most.
She is the biggest Bitch in my world,
But the only friend stuck by my side.
She is my polar opposite,
But also my twin.
She is my greatest enemy,
But will always be my SISTER.
