After marriage, the other man’s wife looks more beautiful.

The line is a wry, cautionary observation about desire and comparison after commitment. It suggests that once someone is married, novelty and the “grass is greener” effect can make other people’s partners seem more attractive than one’s own, not necessarily because they are, but because they are unattainable and free of the daily frictions of married life. In Sidhu’s comic style, the exaggeration works as social satire: it pokes fun at wandering attention and the human tendency to idealize what we don’t have. Read as advice, it implies that contentment in marriage requires resisting comparative fantasies and valuing one’s partner beyond surface allure.
