Mrs. Deane is portrayed as a woman of few words, characterized by her thin lips and careful choice of language. She tends to speak only on special occasions, suggesting she values precision and thoughtfulness in her communication. After speaking, she seeks validation from her husband, indicating a desire for approval and affirmation of her propriety.

This behavior reflects her careful nature and possibly her insecurity, as she desires to confirm that her speeches are appropriate. The dynamic between her and her husband underscores a traditional relationship where she looks to him for reassurance, further highlighting her character's traits in George Eliot's "The Mill on the Floss."
