He, on his part, got angry – pushed away his chair, dragged it back with a cl- ter – trying all the while to control himself; then again he would break out and storm, and wish the whole thing to the devil. As ill-luck would have it, to-day again his daughter answered at random and wrongly. “What an idiot!”he exclaimed, flinging down the book.

They are two of the protagonists of Lev Tolstoy’s War and Peace, finished in 1869.
