Question

comment on the irony of chapter my lost dollar

Answer 1

The author and Todd are good friends. Though the author is unable to forget the loan of a dollar that he had given to Todd he is too decent to ask for a refund. He makes several unsuccessful efforts to remind his friend about the debt. Finally he gives up all hope of getting the dollar back. He thinks that may be he has also similarly forgotten to pay back loans.

While concluding he says that he does not want his 'forgetful' friend Todd to know the torment the non payment has caused him.
