Guess!??

My monotony shears past,

the most lively nights,

teasing child like minds,

to not let me last.

Uneasiness is my jewel,

for the restless souls,

To those enveloped in hell,

Peace- I gift in doles.

You'll find me by lakes and ponds,

disturbed by occasional prods,

of quacks, cackles and chatters,

by ducks, geese and ganders.

I have a song attached to me,

my own music echoes in valleys,

lovers understand my language,

I am appreciated by the wise.

I'm called for by librarians,

Asking for me to be obeyed.

I dare you to break me,

If you'd like to invite unapproving stares.

Harbinger of peace I am,

Sometimes described a deathly blow,

I prevail over the audience of Shakespearean shows.

Hopefully you know me by now,

I majestically declare: Silence I am!
