By free i mean work that is either old enough to be in the public domain, or work that has been presented as free in the first place. Flash fiction is a term used to mean very short literature :)

Here is one by one of its masters, the Lord Dunsany:

The workman

I saw a workman fall with his scaffolding right from the summit of some vast hotel. And as he came down I saw him holding a knife and trying to cut his name on the scaffolding. He had time to try and do this for he must have had nearly three hundred feet to fall. And I could think of nothing but his folly in doing this futile thing, for not only would the man be unrecognizably dead in three seconds, but the very pole on which he tried to scratch whatever of his name he had time for was certain to be burnt in a few weeks for firewood.

Then I went home for I had work to do. And all that evening I thought of the man's folly, till the thought hindered me from serious work.

And late that night while I was still at work, the ghost of the workman floated through my wall and stood before me laughing.

I heard no sound until after I spoke to it; but I could see the grey diaphanous form standing before me shuddering with laughter.

I spoke at last and asked what it was laughing at, and then the ghost spoke. It said: "I'm a laughin' at you sittin' and workin' there."

"And why," I asked, "do you laugh at serious work?"

"Why, yer bloomin' life 'ull go by like a wind," he said, "and yer 'ole silly civilization 'ull be tidied up in a few centuries."

Then he fell to laughing again and this time audibly; and, laughing still, faded back through the wall again and into the eternity from which he had come.

Well, that was a bit depressing... :(

Or perhaps it's supposed to be uplifting, in that it suggests it's still worth striving to achieve things despite their transitoriness. At least I assume that's what it means, although the ghost seems rather inconsistent in its attitude, since he tried to achieve something when about to die, and then laughed at everyone else for doing the same thing over a longer time period.

I'd guess the human who was about to have a fatal SPLAT! tried instinctively for one last shot at immortality, but the ghost realized that human lives/lifespans are so insignificant in comparison to infinity/forever, that striving for immortality while still alive is foolish.

May as well ask the ancient Egyptians why they would bother to build the Great Pyramid or the Sphinx, since human civilizations are so transitory in comparison to all of time.

And yes, I find these thoughts depressing. :(

I too find it a bit sad, but i do not agree with the sentiment of the ghost. Moreover Dunsany has another very short piece in which he seems to defend the opposite notion, i'll see if i can find it :)

And here it is:

The worm and the angel

As he crawled from the tombs of the fallen a worm met with an angel.

And together they looked upon the kings and kingdoms, and youths and maidens and the cities of men. They saw the old men heavy in their chairs and heard the children singing in the fields. They saw far wars and warriors and walled towns, wisdom and wickedness, and the pomp of kings, and the people of all the lands that the sunlight knew.

And the worm spake to the angel saying: "Behold my food."

"Be dakeon para Thina poluphloisboio Thalassaes," murmured the angel, for they walked by the sea, "and can you destroy that too?"

And the worm paled in his anger to a greyness ill to behold, for for three thousand years he had tried to destroy that line and still its melody was ringing in _his head.

Another one of my favourite pieces by him:

Charon

Charon leaned forward and rowed. All things were one with his weariness.

It was not with him a matter of years or of centuries, but of wide floods of time, and an old heaviness and a pain in the arms that had become for him part of the scheme that the gods had made and was of a piece with Eternity.

If the gods had even sent him a contrary wind it would have divided all time in his memory into two equal slabs.

So grey were all things always where he was that if any radiance lingered a moment among the dead, on the face of such a queen perhaps as Cleopatra, his eyes could not have perceived it.

It was strange that the dead nowadays were coming in such numbers. They were coming in thousands where they used to come in fifties. It was neither Charon's duty nor his wont to ponder in his grey soul why these things might be. Charon leaned forward and rowed.

Then no one came for a while. It was not usual for the gods to send no one down from Earth for such a space. But the gods knew best.

Then one man came alone. And the little shade sat shivering on a lonely bench and the great boat pushed off. Only one passenger: the gods knew best. And great and weary Charon rowed on and on beside the little, silent, shivering ghost.

And the sound of the river was like a mighty sigh that Grief in the beginning had sighed among her sisters, and that could not die like the echoes of human sorrow failing on earthly hills, but was as old as time and the pain in Charon's arms.

Then the boat from the slow, grey river loomed up to the coast of Dis and the little, silent shade still shivering stepped ashore, and Charon turned the boat to go wearily back to the world. Then the little shadow spoke, that had been a man.

"I am the last," he said.

No one had ever made Charon smile before, no one before had ever made him weep.
