“(…) there was an old fellow (…) – a man of very great intelligence. Well, he used to say that the great thing in married life was patience. (…) Not love, but patience. Love cannot last long. You have lived two years in love, and now evidently your married life has reached the period when, in order to preserve equilibrium, so to speak, you ought to exercise all your patience.”
“The Duel” by Anton Chekhov
