The essence of a William Trevor short story

William Trevor's story in "Selected Stories" called (I think) Mourning, about a young man in Ireland, youngest in his family, works in construction and is rather unskilled, they joke that he's well-suited to run the cement mixer, leaves for England and better opportunity, and story follows him through his loneliness in London, the butt of bullying jokes on his construction crew, and he's befriended by another Irishman and slowly, subtly recruited to commit a terrorist act (leave bomb on a bus - though it's never made completely clear) - and his decision as to whether to go through with the act will be the most important decision of his life. I won't give it away. But this is another one of the best of Trevor's pieces and typical of the key elements in his fiction: the isolated and somewhat lonely or eccentric individual, the elegaic sense about the doomed nature of current society moving too fast and confusing us with its demands and changes, an undercurrent of contemporary political struggle, the key moment or decision or action that will change the course of a character's life (in this way he differs from Chekhov and other great story-writers and comes closer to the style of a dramatist, or maybe of a moralist). Trevor's characters are all trying to get by in a difficult, changing world, a world that has left them (and rural Ireland, often their homeland) alone and confused and quaint (though not picturesque), and they get by through compromise and accommodation.
