Scars

If our hearts were empty, they wouldn't be full of scars.
But if the sky were empty, we couldn't see the stars.

If we build a wall, we'll never be hurt,
but it we never felt pain, we never would learn.

If fire didn't burn, we'd be colder than ice.
And if scars didn't hurt, we'd make the same mistakes twice.

If the dark were empty, we wouldn't have fears,
but we wouldn't have light to wipe away our tears.
