Sooner or later you will hold someone else's hand, kiss someone else's lips, hold someone else to sleep, and sooner or later I will wear a ring given by someone else, wear a wedding dress ordered by someone else, hold someone else's hand and become someone else's bride. Maybe you will suddenly think of me when you kiss someone else's face, and your smiling face may appear in front of me when I lean on someone else's shoulder, but all this has nothing to do with you and me. This is the cruelty of youth, right?
