If another stanza were added to “The Caged Bird,” which excerpt could best be used to continue the extended metaphor?

The free bird sings
with a joyous song
of the captive life
that kept it safe all along
The caged bird sings
with a fearful trill
of things it craves
outside the sill
The free bird sings
with a fearful trill
of things it craves
outside the sill
The caged bird sings
with a joyous song
of the captive life
that kept it safe all along

The caged bird longs

for the touch of the breeze
that carries whispers of freedom
through the rustling trees
It dreams of soaring high
in the boundless sky above
and spreading its wings wide
in a dance of pure love

To continue the extended metaphor in "The Caged Bird," the excerpt "The caged bird sings with a joyous song of the captive life that kept it safe all along" could be used as a starting point.

To continue the extended metaphor in "The Caged Bird," the next stanza could explore the theme of freedom and its significance to both the caged bird and the free bird.

For example, the stanza could convey something like:

The free bird soars
in the boundless sky
its wings outstretched
as it dances high
The caged bird yearns
for the open sky too
dreaming of flight
its spirit breaking through
The free bird knows
the true meaning of flight
unfettered and pure
in effortless delight
The caged bird longs
to taste freedom's sweet air
its soul in chains
with dreams beyond its lair

In this continued metaphor, the stanza highlights the stark contrast between the free bird's sense of freedom and the caged bird's yearning for it. The free bird's flight is described as boundless and joyous, while the caged bird dreams of breaking free from its confinement to experience the same sense of liberation.
