My parents once cherished me like a treasure, but when I turned down the air conditioner by one degree to take care of my sister, they locked the five-year-old me in a powerful refrigerator. They lavished their care and concern on my sister, completely forgetting about my existence, until a neighbor pried open the door and rescued me, barely alive. They knelt and wept in remorse, but the coldness you gave me is more piercing than the refrigerator.
