Boundless or Not

Why is a string with a free end so different?
It has freedom, but it comes with domain.
Can string ever be free without limit?

The Fates always carried around theirs taut
But when it came time for the human, pain.
Why is a string with a free end so different?

America, how much should we be bent
Living life on the free but empty lane?
Can string ever be free without limit?

When the soul of a lab mouse goes silent:
Protest, but the caged soul is fine and sane.
Why is a string with a free end so different?

How open shall the journey road reach out
Without ending in the sorrow and rain?
Can string ever be free without limit?

Execution of men is explicit,
And yet life lived in prison is humane.
Why is a string with a free end so different?
Can string ever be free without limit?
