My Sister Is Jealous Of Me Because I'm My Parents’ Favorite

My name is Zoe. I’m fifteen. This is my sister, Daphne, who’s 3 years younger than me. I love her very much and I think she loves me, too. I mean, we’re sisters. But, unfortunately, Daphne is very jealous of me. Do you want to know why? Because I’m my parents’ favorite! Our parents love me more and that’s why Daphne is so annoyed with me. But please tell me one thing: How is this my fault?
