That's how stories happen - with a turning point, an unexpected twist. There's only one kind of happiness, but misfortune comes in all shapes and sizes. It's like Tolstoy said. Happiness is an allegory, unhappiness a story.
The essence of storytelling lies in the presence of turning points and unexpected twists, which propel the narrative forward. While happiness is a singular concept, misfortune appears in myriad forms. This highlights the complexity of human experiences, where joy is simple yet fleeting, while struggles create a richer tapestry of life's stories.
