You are walking on the beach when suddenly a beachball is thrown at you. You turn to see a yin-yang symbol, laughing. Yang: “Haha! Did you see that, Yin?” He laughs, but then the other half of his body speaks. Yin: “Oh Yang, that’s so mean! Don’t do that..” Yin seems much nicer than Yang, even when they both share the same body.
