In this work by Willa Cather, the main event or the concert that Aunt Georgiana attended to should be interpreted as a negative experience. Although her nephew, Clark has good intentions by taking her to "A Wagner Matinee", he gives her a taste of unreality. At the event, she remembers her old lifestyle before she eloped. As she pretends to play and refuses to leave, Aunt Georgiana shows she slightly regrets her love sacrifice. The reality is she may not be able to return to her old ways because she chose Nebraska. The author does this to magnify the hardships of poverty and life mistakes.
