My mom found an expert to calculate the best delivery dates for the babies my sister and I were carrying. He claimed that if the babies were delivered by C-section at that time, they would definitely be child prodigies. I flatly refused. A premature baby might not even be healthy, so what good would being smart do? Seeing how resolute I was, my sister suppressed her own urge and refused too. Later, we both gave birth at full term, but my sister thought her child wasn't smart enough and was far too ordinary. “My child should have been a prodigy, but now he's so average. It's all your fault for refusing to deliver early. You made me miss my chance too!” As the child grew up, my sister struggled to tutor him. Eventually, she broke down, came to my house, and set a fire that killed us both. When I opened my eyes again, I was back on the day my mom asked the expert to calculate our delivery dates. Beside her, my sister was gazing at her with shining eyes.
