It used to seem to me an impossibility to learn a whole piece of music by heart; but now, when I knew that he would hear it and might praise it, I would play a single movement forty times over without stopping, till poor Kátya stuffed her ears with cotton wool, while I was still not weary of it. The same old sonatas seemed quite different in the expression, and came out quite changed and much improved. Even Kátya, whom I knew and loved like a second self, became different in my eyes. I now understood for the first time that she was not in the least bound to be the mother, friend, and slave that she was to us. Now I appreciated all the self-sacrifice and devotion of this affectionate creature, and all my obligations to her; and I began to love her even better. It was he too who taught me to take quite a new view of our serfs and servants and maids. It is an absurd confession to make⁠—but I had spent seventeen years among these people and yet knew less about than about strangers whom I had never seen; it had never once occurred to me that they had their affections and wishes and sorrows, just as I had. Our garden and woods and fields which I had known so long, became suddenly new and beautiful to me. He was right in saying that the only certain happiness in life is to live for others.
