Final answer:
The provided text does not relate to the short story 'To Lotti with Love', so it's not possible to accurately analyze the irony in the letter found in the hat. References from other literary works have incorrectly been associated with this story.
Step-by-step explanation:
The question seems to be about the ironic element found in a letter within the story To Lotti with Love. However, there's confusion as the provided references do not directly relate to the story mentioned but are from various different literary works.
The excerpts include a conversation from A Doll's House by Henrik Ibsen, a comment on Dorothy Wordsworth's attitude towards the poor, a narrative from William Dean Howells' story where Editha's romanticized view of war is confronted with reality, a discussion on the irony in Jane Austen's narrative voice, and a passage about Fitzgerald's storytelling and his views on wealth and disillusionment.
Without the specific text of To Lotti with Love, we cannot provide a factual and accurate explanation of the irony in the letter found in the hat. Therefore, it's necessary to refuse to answer this part of the question due to a lack of relevant and precise information.
