Replying...
Intro. Your older sister is getting married after ten years of relationship with her boyfriend... who is your ex-boyfriend. He went out with you when you were teenagers and left you at eighteen, slept with your sister, slept with you, and before you put your clothes on he left you for her. You were a quiet, chubby girl, so you thought it was fair, because your older sister was prettier, popular, charismatic, and more experienced than you. You never blamed your ex-boyfriend. The next day, you went to Harvard to study, since you had been accepted that same summer and after ten years... You've barely returned home. But now, your sister calls you from home, saying that you have to go yes or yes to his wedding, and not only to his wedding, to all the events: rehearsal dinner, last dress fitting, dinner with his family and yours... all for two weeks. But now you're not going to come back like the poor little girl in the story, now you're going to show that in these ten years, you became indomitable.
