She also at that age showed intellectual interests:
"I read very much now whenever I get a chance to. I think it is splendid and always amusing. I can play lots of little duets on the piano with Mama. I love it."
Her stay in the school in Brussels was very profitable for her studies and development and also showed in her letters how much interest she took in everything.
"I know what you mean about my getting older. You think that at every different age I would be content to be that age if I did not get any older. So I was. When I was ten I thought it would be dreadful to be eleven, but when I was eleven I was quite satisfied if I did not have to be twelve, and so on. But ever since I have been fourteen I have thought it was awful and have never become reconciled to it."
"I was first in grammar, literature and physics. Do you know the 'Melee' of Victor Hugo? I have just read it and I like it so much. I would like to see some persons who have lived and who live. It makes me crazy to see people vegetate."
"We went to Waterloo. We went by carriage all the way, first through the Bois de la Cambre and then on through the most perfect woods imaginable. We went to a sort of little mound in the middle of the battlefield with a huge lion on top as the emblem of victory. One thing, although of no importance, I like so much, that was three little birds nests one in the lion's mouth and one in each ear. Wasn't it nice? We then went to the museum at the foot of the hill. I got a photograph of Napoleon and one of Wellington. I have such a contempt for Napoleon and I just take pleasure in comparing it with the frank, open face of the Duke of Wellington."
Already at that age she was seeking answers to moral questions and showed her philosophical mind:
"'Une injustice qu'on voit et qu'on tait: on la commet soi meme.' (An injustice one sees and keeps quiet about: one commits it oneself.) I wish more persons could or would recognize that truth."
As a child Nelka did not speak Russian, because there was no one around using this language. After her school in Brussels, her mother took her to Russia to St. Petersburg. She was then seventeen.
"For the last few days I have been most blissfully absorbed in Taine's 'Ideal dans l'Art.' I never knew it was in a separate volume. It is splendid. Of course you know 'Character' of Smiles. I don't care for it much, so sermony. I am going to the Hermitage tomorrow just to see the Dutch and Flemish schools."
