Read the following stanza from audre lorde's poem "hanging fire" and answer the question.

i am fourteen
and my skin has betrayed me
the boy i cannot live without
still sucks his thumb
in secret
how come my knees are
always so ashy
what if i die
before morning
and momma's in the bedroom
with the door closed.

what of the following is a symbol for separation and disconnection?

her knees
the closed door
the morning
the secret
