@reddit88388: My parents made me and my sister take turns being their only daughter, Sophie. Every month, while the other had to live in the basement and pretend she didn't exist. When I got sick during an off-month and started vomiting blood, they gave us seven days to decide which sister they'd kill with pills, so they could finally have just one daughter. But we tricked them into thinking we'd both been poisoned and escaped while they panicked.
