What does the stranger do that saddens elisa?

In John Steinbeck's "The Chrysanthemums," the stranger's visit saddens Elisa because he dismisses her chrysanthemums, the flowers she takes pride in, as mere objects of commerce rather than appreciating their beauty and her passion for gardening. His lack of genuine interest and understanding of her talents makes Elisa feel undervalued and invisible. This encounter deepens her sense of isolation and longing for connection, highlighting her unfulfilled desires.
