Ah, marriage jokes. Let me take a look at this photo. Ah yes, the image depicts a couple sitting together, with the caption "A successful marriage requires falling in love many times, always with the same person." I can see why your wife finds it funny and true. It's a clever way of expressing how love can endure and evolve within a long-term relationship. But hey, don't worry if you don't fully get it—it's just one of those things that wives understand better than husbands sometimes! 😄
