The small stone fell from a ledge in a study somewhere and dropped into a travel bag.
Later the bag was picked up and carried away.
Much later still it was put in a car being placed on the back seat. The car was then driven to a port where it was taken off the seat of the car and carried on-board a cruise ship. The cruise ship was about to sail up the Norwegian Fjords. It sailed there quite frequently, though not exclusively as it also sailed around the Mediterranean Sea.
The bag was taken to and placed in one of the luxurious staterooms.The owner of the bag and her husband were celebrating an important event by enjoying a journey that they had always promised themselves. The bag eventually ended up on the deck as the husband had fetched it for his wife for an object that it contained. In getting that thing out, the small stone got caught up in it somehow and was pulled out of the bag and fell onto the deck of the ship, whereupon it started to roll about.
Ultimately the stone found its way to the stairs down to the lower deck where it found a gap to lodge in. The cruise ship sailed into the fjords during a sudden heavy storm causing much turbulence not only on the ship but in a number of the passengers stomachs, one of whom, a drinking man I chance, could not contain himself, and he was violently sick. The storm abated however, and all was well.
A crewman took on the task of cleaning up after the apparently bibulous gentleman and washed down the deck, and in doing so, washed the small stone through a gap, specially there for the deck washing purpose, and into the fjord whereupon it sank to the very deep bottom.
Such are the mysteries of life, but in that one pebble's journey you can gauge the unpredictable future of every man, woman and child and creature on Earth.
Isn't life utterly bewildering?
It is unlikely that the ever-moving tides in the fjord will not have moved it elsewhere many times since it fell in off the ship, out of the bag, out of the car, into the car, into the bag, and off the shelf in the first place.
How it arrived on the shelf is a story for another day.
