The Two Destinies by Wilkie Collins, Fiction 12+

📘 My wife, in her impulsive way, forgot the formalities proper to the occasion, and kissed her at parting. At that one little act of sisterly sympathy, the fortitude which the poor creature had preserved all through the evening gave way in an instant. She burst into tears. I felt as fond of her and as sorry for her as my wife. But (unfortunately) I could not take my wife's privilege of kissing her. On our way downstairs, I found the opportunity of saying a cheering word to her husband as he accompanied us to the door. "Before I open this," I remarked, pointing to the portfolio under my arm, "my mind is made up, sir, about one thing. If I wasn't married already, I tell you this -- I should envy you your wife." He pointed to the portfolio in his turn.
