My sister is the sister of someone else,
not the real one, the other one.
but she has become my sister.
My real sister, who is really my big sister
divorced me after our mother died.
My other big sister, who was my friend at the time
adopted me as her little sister.
Her little sister, her real little sister,
divorced her when their father died.
I do not know if my big sister or her little sister
have any other sisters.
But my new big sister and I call each other
‘My Sister” and we like that very much.
