“She used the formal mode of address in speaking to Lubkov, and when she was going up to bed she said good-night to him exactly as she did to me, and their rooms were on different floors. All this made me hope that it was all nonsense, and that there was no sort of love affair between them, and I felt at ease when I met him. And when one day he asked me for the loan of three hundred roubles, I gave it to him with the greatest pleasure.”
