I vividly remember the day Olivia came into the world. My mother gave birth prematurely. Olivia weighed less than two kilos and spent nearly a month in an incubator. The doctors said she was frail, her lungs underdeveloped. From that moment, our family’s life revolved around her like a planet orbiting the sun.

“Aiden, be gentle,” my mother would always remind me. “Your sister is very weak.”

“You’re the big brother,” my father would say. “You have to set an example.”
