At my house, every time my sister and I have a dispute, we settle it with a game of 'King's Game'. Whether it's a fight over snacks, the order of taking a bath, or whether to get a dog or a cat. That rule hasn't changed even now that my sister has grown up. The orders are absolute, so you can do anything. When my brother wins, he immediately makes me lick his penis, but when my sister wins, it turns into a handjob halfway through, that's the kind of battle we play out every day.
