How is irony expressed in the story ”one thousand dollars”?

There are three instances of irony in the story "One Thousand Dollars":

Explanation:

It is ironic that Young Gillian does not grumble about inheriting only one thousand dollars when he has been entirely dependent upon his uncle's wealth. It is ironic that Young Gillian is unselfish in his efforts to spend the money, rather than spending it on himself as has been his habit. It is ironic that when seemingly self-gratifying Gillian learns that his act of being unselfish will earn him a larger inheritance, he falsifies his report so that the young woman he loves will be given the money instead.
