The irony was painful. Throughout undergraduate studies at Ohio State, I maintained a perfect GPA while working part-time to cover expenses. Jessica struggled with organic chemistry and physics, requiring expensive tutors our parents readily provided. When she needed to retake the MCAT, they paid for an exclusive Prep course. When I scored in the 98th percentile on my first attempt, they simply nodded and said, “that’s nice, dear.”

Despite everything, I never resented Jessica. She was my sister, my twin, and I loved her. She didn’t create our parents’ favoritism; she just benefited from it. Sometimes I even thought she felt uncomfortable with their obvious preference, though she never said anything directly.
