Riddle -A Muse

Riddle - A Muse

I can be ignored with a frown,
not shunned nor shouted down.
Brought to my shaking knees,
with yearning midnight pleas.
Left out desperate in the rain,
steeping in my boiling pain.
Leashed and I cry for release,
and choke until my sobs cease.

Too strong to succumb to abuse,
I'm lore's all encompassing muse.
Commit murder to me some more,
yet still you'll crawl across my floor.
I'm emotions noblest pinnacle,
when you are jaded I am simple.
Chastise me with punishing whys,
then see warm hope soften my eyes.

Whether crying,
or sighing,
What am I?
