Customary.

Responsibility.  Noun.  A detachable burden easily shifted to the shoulders of God, Fate, Fortune, Luck or one's neighbor. In the days of astrology it was customary to unload it upon a star. 

Ambrose Bierce

Presages.

Enthralled by some mysterious spell, I stood
In the lit gloom of an enchanted wood.
The cypress there and myrtle twined their boughs,
Significant, in baleful brotherhood.

The brooding willow whispered to the yew;
Beneath, the deadly nightshade and the rue,
With immortelles self-woven into strange
Funereal shapes, and horrid nettles grew.

No song of bird nor any drone of bees,
Nor light leaf lifted by the wholesome breeze:
The air was stagnant all, and Silence was
A living thing that breathed among the trees.

Conspiring spirits whispered in the gloom,
Half-heard, the stilly secrets of the tomb.
With blood the trees were all adrip; the leaves
Shone in the witch-light with a ruddy bloom.

I cried aloud! -- the spell, unbroken still,
Rested upon my spirit and my will.
Unsouled, unhearted, hopeless and forlorn,
I strove with monstrous presages of ill!

At last the viewless --

Shishkin, The Forest of Countess Mordvinova, 1891

From the vast, invisible ocean of moonlight overhead fell, here and here, a slender, broken stream that seemed to plash against the intercepting branches and trickle to earth, forming small white pools among the clumps of laurel. But these leaks were few and served only to accentuate the blackness of his environment, which his imagination found it easy to people with all manner of unfamiliar shapes, menacing, uncanny, or merely grotesque.

He to whom the portentous conspiracy of night and solitude and silence in the heart of a great forest is not an unknown experience needs not to be told what another world it all is - how even the most commonplace and familiar objects take on another character. The trees group themselves differently; they draw closer together, as if in fear. The very silence has another quality than the silence of the day. And it is full of half-heard whispers, whispers that startle - ghosts of sounds long dead. There are living sounds, too, such as are never heard under other conditions: notes of strange night birds, the cries of small animals in sudden encounters with stealthy foes, or in their dreams, a rustling in the dead leaves - it may be the leap of a wood rat, it may be the footstep of a panther. What caused the breaking of that twig? What the low, alarmed twittering in that bushful of birds? There are sounds without a name, forms without substance, translations in space of objects which have not been seen to move, movements wherein nothing is observed to change its place. Ah, children of the sunlight and the gaslight, how little you know of the world in which you live!
