What is the Author's tone in the story, The Woman at the Store?

Mansfield subtly shows that the protagonist is duplicitous through the contrast between the tone of her inner thoughts and that of her dialogue. During her personal reflection, the protagonist concludes that the woman is certainly “mad” (63). However, when talking to the woman, the protagonist “smiled at her” (63) at the end of her sentences. This shows that the protagonist wants to outwardly portray herself as pleasant, but in truth, she is more judgmental.
