Kiss and Tell

A brilliant review of Chekhov's short story, The Kiss. Highly recommended (the story, not the review; though that too!)

Another interesting parallel (though a somewhat darker one) could be with Part II of Dostoevsky's Notes from Underground where the narrator becomes totally obsessed with some small slight that an officer has done him (he brushed him aside without seeming to notice him), and spends years moping about it, planning his revenge - which consists finally of nothing more drastic than bumping into the officer on the street one day! There is the same sense of a trivial incident that no one else cares about or has even noticed, becoming inflated in the narrator's mind to become almost the purpose of his life.
