What's underused by Americans?
Underused by Americans,
Lucky from below an animal,
Plucking at your tin cans,
Sequential in this riddle.
Do you know what I am?
Can you find my shape?
If so, you truly know yourself.

A Void in my Heart

Avert the kids vocalizing with the tv set,
Silence the ringtones and with quiet song

Riddle... I am like a dear halo
I am like a dear halo,
Plucked from a rainbow,
A tight noose brings me to life,
With the repeated stab of a knife,
Old grief of the elephants,
Holy like the elements,
I penetrate a scar of my soft master,
I elude many, you better run faster.
