“Good night, good night! Parting is such sweet sorrow,
That I shall say good night till it be morrow.”
This is line from William Shakespeare’s Romeo and Juliet. Juliet says this to her lover Romeo. Although she is sad she has to say goodnight, she is also excited for the next time she will see him again. It was a sweet goodbye.
This line stayed relevant over the years because it embodied the passion and romance the play was famous for. It represented the tragedy that comes with love, the sadness that must come with happiness. It epitomized the mixed emotions in a relationship that people from all across generations can relate to.
