I also know why the caged bird sings.
He does so because the bars were forged in hatred,
and the whole world has turned into a simple room,
as when your eyesight only reaches the horizon,
and you can’t walk past it anymore, you forget 
there was anything ahead of it. The caged bird sings
because he thinks he chirps the truth, yet they are lies,
propaganda repeated from who first captured him.
The caged bird sings because blindly repeating
what he once heard like a mindless parrot
gives him a fake sense of freedom, 
even when his only prison is his own mind.
