We are in Volume II, Part Five, Chapter XXII. This is a very important scene as we see Natasha (after "the fall") alone in a drawing room with Pierre. You can see that Pierre has so much empathy for her, unlike everyone else. He even asks if she loved Anatole, although he refers to him as "that bad man".
"Up until then he had reproached her in his soul and had tried to despise her; but now he felt such pit for her that there was no room in his soul for reproach."
I used a bit of English text here, from a thesaurus. One of the words are "boredom"; "weariness"; "tedium", "heavy hours". This captures Natasha's emotional state. -- Lola
