Which detail best conveys a mood of loneliness?
the open boat

by stephen crane (adapted excerpt)

the cook's arm was around the oiler's shoulders, and, with their fragmentary clothing and haggard faces, they were the babes of the sea, a grotesque rendering of the old babes in the wood.
later he must have grown dull at his work, for suddenly there was a growling of water, and a crest came with a roar and a swash into the boat, and it was a wonder that it did not set the cook afloat in his life belt. the cook continued to sleep, but the oiler sat up, blinking his eyes and shaking with the new cold.
"oh, i'm awful sorry, billie," said the correspondent contritely.
"that's all right, old boy," said the oiler, and lay down again and was asleep. presently it seemed that even the captain dozed, and the correspondent thought that he was the one man afloat on all the oceans. the wind had a voice as it came over the waves, and it was sadder than the end.
