What does the sentence thought was almost revolting mean in khushwant singhs portarait of a lady mean?

You are referring to a sentence from Khushwant Singh's short story "Portrait of a Lady," but you have only provided a fragment.

To understand what "thought was almost revolting" means, I need the full context of the sentence.

Please provide the complete sentence from the story. That will help me explain what the sentence means within the context of the story.
