'My Lost Dollar' is one of Stephan Leacock's short stories, which is his inimitable comic style. In the story, the narrator has lent a dollar to his friend, about which the latter seems to have forgotten. The narrator often mentions it in his conversations, with the friend, in hope of making him recollect the debt. Finally, he gives up the expectation of getting it back as he comes across a painful thought- like his friend, he might also have forgotten to pay back odd dollars he'd once borrowed from people. Leacock reflects in the story, the incongruities of life, as well as human hypocrisy and pretence. Hope the answer helps! Cheers!
